v 0.7.5, June 20 2001
* Gawk 3.1.0's Coprocessing and inet functions are now supported by Awka,
as are the new builtin functions asort() and mktime(). Thanks to Juergen
Kahrs for the original work to implement this excellent feature, and to
Arnold Robbins for including it in Gawk. That libawka will now be
distributed under the GNU General Public License (GPL) rather than
LGPL as a result of having to include some code from Gawk. The previously
separate dfa library is now absorbed into libawka, and the -d command-line
option for awka removed as it is no longer needed.
so revise the PLIST, removing dfa.h and libdfa.a accordingly

From CHANGELOG.txt:
v 0.7.5, June 20 2001
* Gawk 3.1.0's Coprocessing and inet functions are now supported by Awka,
as are the new builtin functions asort() and mktime(). Thanks to Juergen
Kahrs for the original work to implement this excellent feature, and to
Arnold Robbins for including it in Gawk. That libawka will now be
distributed under the GNU General Public License (GPL) rather than
LGPL as a result of having to include some code from Gawk. The previously
separate dfa library is now absorbed into libawka, and the -d command-line
option for awka removed as it is no longer needed.
* The match() function has been extended to support its new capability in
Gawk 3.1.0. See the Gawk manpage for details.
* awka -a -v 'var="string with whitespace"' will now work correctly.
* To avoid breaching ANSI-C guidelines, \r in AWK program strings will
be preserved as \r in the generated C code, not converted to ASCII
character 13. Previously some platforms were incorrectly treating
\r as \n - this has been fixed by this change.
* Fixed a problem wherein awka -c sometimes failed to output matching
curly braces in the translated code.
* Fixed a data-input parsing error that could occur when RS="". The new
test rsnul1nl (from gawk-3.1.0) will ensure the buglet doesn't return.
* A new hash routine was implemented providing fewer collisions, particularly
with long string indexes that have only minor differences. The optional
SLOW_HASH #define is no longer needed.
* Translator now tracks the datatype of scalar variables, and will produce
more efficient code for vars that stay one type throughout a script.
This is the first optimisation of translated code in a long, long time
and it makes a considerable difference to many scripts.

Changelog:
v 0.7.4, June 12 2001
* Regular expressions that are exact strings will now run much quicker.
* Tidied up some loose threads in lib/rexp.c.
* FIELDWIDTHS will no longer be used in calls to the split() function,
but only with the parsing of $0 into the $1 ... $n fields.
* Removed the unnecessary VERSION line from configure.
* Removed the 'longwrds' test's reliance on the sort utility.
* Dropped the 'nasty' test. It doesn't accomplish much and fails
on many systems (as it does for gawk).
* Altered the test suite so it will always use the static library
rather than the shared-object one. This was necessary to allow "make test"
to work if the package hadn't previously been installed.
v 0.7.3, May 25 2001
* A shared object version of libawka will be compiled on systems that
support it.
* "var=value" without a preceding -v is now supported.
* awka's "-o filename" will now produce a C file called "filename.c",
instead of defaulting to awka_out.c as it did previously.
* awka's -- option now works again, as will --help.
* The third parameter of Gensub now works if it is a number > 0.
* "." no longer required in PATH to run the test suite.
* Array element deletions will no longer leak memory like a sieve.
* The extended function alength() wasn't accounting for array element
deletions - now it does.
* various code cleanups, and better support for C++ compilers.
* split("",array,whatever) will now return 0 instead of 1.
* fixed a memory fault that sometimes occurred when arrays created by
split() were extended.
* nextfile and next from with a function now supported.
* The builtin function system() will now fork()/execl() processes, and
you can define which shell program it uses. See INSTALL for more details.
I haven't implemented this for piped input (eg. "sort abc" | getline) yet.
* Added John Maybury's fix for a problem in the temporary variable stack.
* Libawka will now compile with SLOW_HASH defined.
* Eliminated the annoying compile warnings for redefinition of BEGIN and END.
* SUBSEP wasn't being picked up as an internal variable by the translator!
This error corrected.
* Relaxed the temporary variable pool optimisation introduced in 0.7.2, as
it was occasionally overdoing it & causing buggy behaviour.
* Fixed a bug that caused getline to sometimes fail to set the value of $0.
v 0.7.2, August 26 2000
* Added to the test suite about a dozen or so new scripts borrowed from
gawk-3.0.6.
* Corrected awka's handling of code like b += b++, the problem being that
AWK's handling of post & pre increment and decrement operators is actually
different from how C does it, which isn't what I expected.
* Optimised the size of the temporary-variable pools, so that it doesn't
create more variables than your program needs. This reduces memory
requirements, and can significantly improve performance.
v 0.7.1, August 15 2000
* Introduced a structure containing names & pointers to user-defined
functions, for potential use in extended library code.
* Found and fixed some memory leaks stemming from how the new dfa library
was integrated with awka.
* Some code cleanup to make gcc -Wall a bit happier (but still not
warning-free).

changed to the link given on the home page, but all the links for
pre-0.7.2 versions are dead _there_.
Oh well. I tried.

+ move the patch digest/checksum values from files/patch-sum to distinfo

package Makefile.
