Several changes are involved since they are all interrelated. These
changes affect about 1000 files.
The first major change is rewriting bsd.builtin.mk as well as all of
the builtin.mk files to follow the new example in bsd.builtin.mk.
The loop to include all of the builtin.mk files needed by the package
is moved from bsd.builtin.mk and into bsd.buildlink3.mk. bsd.builtin.mk
is now included by each of the individual builtin.mk files and provides
some common logic for all of the builtin.mk files. Currently, this
includes the computation for whether the native or pkgsrc version of
the package is preferred. This causes USE_BUILTIN.* to be correctly
set when one builtin.mk file includes another.
The second major change is teach the builtin.mk files to consider
files under ${LOCALBASE} to be from pkgsrc-controlled packages. Most
of the builtin.mk files test for the presence of built-in software by
checking for the existence of certain files, e.g. <pthread.h>, and we
now assume that if that file is under ${LOCALBASE}, then it must be
from pkgsrc. This modification is a nod toward LOCALBASE=/usr. The
exceptions to this new check are the X11 distribution packages, which
are handled specially as noted below.
The third major change is providing builtin.mk and version.mk files
for each of the X11 distribution packages in pkgsrc. The builtin.mk
file can detect whether the native X11 distribution is the same as
the one provided by pkgsrc, and the version.mk file computes the
version of the X11 distribution package, whether it's built-in or not.
The fourth major change is that the buildlink3.mk files for X11 packages
that install parts which are part of X11 distribution packages, e.g.
Xpm, Xcursor, etc., now use imake to query the X11 distribution for
whether the software is already provided by the X11 distribution.
This is more accurate than grepping for a symbol name in the imake
config files. Using imake required sprinkling various builtin-imake.mk
helper files into pkgsrc directories. These files are used as input
to imake since imake can't use stdin for that purpose.
The fifth major change is in how packages note that they use X11.
Instead of setting USE_X11, package Makefiles should now include
x11.buildlink3.mk instead. This causes the X11 package buildlink3
and builtin logic to be executed at the correct place for buildlink3.mk
and builtin.mk files that previously set USE_X11, and fixes packages
that relied on buildlink3.mk files to implicitly note that X11 is
needed. Package buildlink3.mk should also include x11.buildlink3.mk
when linking against the package libraries requires also linking
against the X11 libraries. Where it was obvious, redundant inclusions
of x11.buildlink3.mk have been removed.

Patches from Nathan Langford via PR pkg/19580.
Changes:
RELEASE 1.0.3
=============
- All ANSI C incompatibilities should be fixed. Please report any that
remain.
- Various bugs encountered when building gnuboy on strange compilers
have been fixed.
- Internal support for decompressing gzipped roms now exists in a
minimal form. The inflate code used is taken from a quine
(self-reproducing program) written by David Madore and placed in the
public domain. This code is very portable but is rather slow and may
crash when given invalid data; however, there should be no impact on
security. Currently only gzip files (not pkzip files) are supported.
- HuC3 emultaion has been fixed to some extent. Robopon Sun and Star
are both playable now, but many features of the HuC3 are still not
implemented.
- Color filtering to make gnuboy look much more like a real CGB is now
included, thanks to the work of Jonathan Gevaryahu.
- A new rcvar "gbamode" has been added to unlock the GBA-only features
present in some newer CGB games. (This has nothing to do with GBA
emulation, which gnuboy does not do and will not do in the future.)
- Sprite sorting in DMG mode has been fixed. This should improve things
in various DMG games where sprites previously overlapped in the wrong
order.
RELEASE 1.0.2
=============
- A minor problem in the frequency sweep function on sound channel 1
was fixed, correcting the sound of the ice beam and metroid encounter
sound in Metroid 2.
- Sound channel 3 waveform data is now trashed when the sound is
played. This makes it more difficult for games and demos to detect
that they are running on an emulator.
- The channel 3 waveform is now properly initialized in both DMG and
CGB modes. Before it was incorrectly initialized to have frequency
16 times too high, and the initial "random noise" pattern exhibited
by DMG wasn't emulated. R-Type now sounds much better.
- The sound length register for channel 3 now works properly, fixing
the title screen music in MegaMan 2. No thanks to gbspec.txt for
having blatently wrong info about this matter.
- Major problems with sound quality on channel 4 (noise) have been
fixed, and the pseudorandom sequence has been replaced to very
closely resemble that of a real Gameboy, thanks to the hard work
of Lord Nightmare. All these changes make a significant improvement
in many games, notably Metroid 2, Final Fantasy Legend II and III,
Camp Deadly, and Wario Land.
- Stereo channels are no longer backwards.
- The DMG STAT register write bug, which causes an interrupt if the
STAT register is written while in HBLANK or VBLANK, is now emulated.
This fixes Legend of Zerd and probably any other DMG game that will
not run on a real Gameboy Color.
- A hack/potential fix for a problem that kept Konami Collection Vol
1 from working has been put in place.
- A major interrupt bug that prevented Amazing Penguin from running
has been fixed.
- Several bugs that could have resulted in crashes under strange
circumstances have been fixed.
- Other minor sound issues have been tweaked or fixed.
RELEASE 1.0.1
=============
- Keys that didn't work in the SDL-based ports have now been fixed.
- The --bindir= option to the configure script now works properly.
- Running "make install" no longer fails when the destination
directory doesn't already exist.
- Various minor cleanups.
RELEASE 1.0.0
=============
- Auto-loading rc files on a per-rom basis.
- Less intense yellow in the default mono palette.
- Default keybindings no longer use modifier keys.
- Lots of new documentation.
- Hardware scaling on matroxfb now looks better.
- Disabled some useless optimizations to work around a bug in gcc
2.96, which despite being a broken compiler has become rather
popular since Redhat decided to package it without sufficient
testing. This will fix the problems lots of people have reported
when compiling.
- Added --disable-arch option to configure to prevent the binaries
built from being dependent on the exact host cpu they're built on.
This will allow distro maintainers to build packages that work even
on older cpus.
