Changes:
- Changed unfactoring to improve simplification (again). This was a
bug fix (first one in a long time).
- Restored "epsilon" to original value in version 10.9b. Required
for factoring large polynomials.
- Changed factor_times() to preserve divides. This improved the
"unfactor" command.
- Added polynomial factoring to the very beginning of "simplify"
command. This is necessary in case you "unfactor" a complicated
equation, then "simplify".

USER-VISIBLE CHANGES
o Underscore '_' is now allowed in syntactically valid names, and
make.names() no longer changes underscores. Very old code
that makes use of underscore for assignment may now give
confusing error messages.
o Package 'base' has been split into packages 'base', 'graphics',
'stats' and 'utils'. All four are loaded in a default
installation, but the separation allows a 'lean and mean'
version of R to be used for tasks such as building indices.
Packages ctest, eda, modreg, mva, nls, stepfun and ts have been
merged into stats, and lqs has been returned to MASS. In all
cases a stub has been left that will issue a warning and ensure
that the appropriate new home is loaded. All the time series
datasets have been moved to package stats. Sweave has been
moved to utils.
Package mle has been moved to stats4 which will become the
central place for statistical S4 classes and methods
distributed with base R. Package mle remains as a stub.
Users may notice that code in .Rprofile is run with only the
new base loaded and so functions may now not be found. For
example, ps.options(horizontal = TRUE) should be preceded by
library(graphics) or called as graphics::ps.options or,
better, set as a hook -- see ?setHook.
o There has been a concerted effort to speed up the startup of
an R session: it now takes about 2/3rds of the time of 1.8.1.
o A warning is issued at startup in a UTF-8 locale, as currently R
only supports single-byte encodings.
plus many new features and bug fixes.

Changes:
- Removed some simplification optimizations in favor of correctness
and simpler code. Minor slowdown.
- Doubled "MAX_COMPARE_TERMS".
- Simplify order poly_div then smart_div reversed.
- Kludge for size checking in poly_div removed.
- Broke "am.in". Edited.
- Added "simplify poly" option to do poly_div first.

Changes are bug-fixes mostly, but also synchronizes bundled GD
with GD 2.0.22 and updates PCRE to version 4.5. Several NetBSD
patches were integrated too, so future pkgsrc updates would
be even more smooth.

DIST_SUBDIR=${PKGNAME}). The author made functional changes without
bumping the version number. :(
This closes PR pkg/25258.

Changes since 10.9b:
- Removed more MS-DOS specific code; functionality improved.
- Implemented what I call "fraction slack". This perfects float to
fraction conversion, and now Mathomatic doesn't rely on perfect
floating point routines. "-O" option added to CFLAGS in file
"makefile" (we can do this now).
- Changed modf() to fmod() where possible.
- Accuracy increased one more digit by reducing the "epsilon" variable.
- Cleaned up "makefile".
- Took a step towards internationalization with gettext(3) by
calling _() for all English strings. Everything ported except for
the "help" command.
- Commented out some unfactoring code that wasn't helpful and took out
the "pause" command from "all.in" for easier testing.
- Rearranged "simplify" command to simplify better.
- Removed some more unfactoring code and made simplification much
better. Go figure. Perfection has been achieved.
- Added "unfactor fully" option.
- Added "make test" to fully test Mathomatic after compilation.
- Removed masking of 8th bit in all Mathomatic input.
- Updated primes program with a nice user interface.
