* Minor syntax cleanups in the manual
* In non-maintainer mode set NDEBUG to disable assert()
* Performance improvements in strcache:

string into the strcache. As a side-effect, many more structure members and
function arguments can/should be declared const.
As mentioned in the changelog, unfortunately measurement shows that this
change does not yet reduce memory. The problem is with secondary expansion:
because of this we store all the prerequisites in the string cache twice.
First we store the prerequisite string after initial expansion but before
secondary expansion, then we store each individual file after secondary
expansion and expand_deps(). I plan to change expand_deps() to be callable
in either context (eval or snap_deps) then have non-second-expansion
targets call expand_deps() during eval, so that we only need to store that
dependency list once.

Plus some from the mailing list.
Imported a patch from Eli to allow Cygwin builds to support DOS-style
pathnames.
- Add more warnings.
- Rename variables that mask out-scope vars with the same name.
- Remove all casts of return values from xmalloc, xrealloc, and alloca.
- Remove casts of the first argument to xrealloc.
- Convert all bcopy/bzero/bcmp invocations to use memcp/memmove/memset/memcmp.
- Apply a fix for the "thundering herd" problem when using "-j -l".
This also fixes bug #4693.
- Fix bug #7257: allow functions as ifdef arguments
- Fix bug #4518: make sure we print all double-colon rules with -p.
- Upgrade to autconf 2.58/automake 1.8/gettext 0.13.1
- Various doc cleanups, etc.
enable the automake ansi2knr capability.
Right now this doesn't quite build using a K&R compiler because of a
problem with the loadavg test program, but the rest of the code works. I'm
asking the automake list about this problem.
Invent a new macro HAVE_DOS_PATHS and change various instances of:
#if defined(WINDOWS) || defined(__MSDOS__)
to use the new macro instead. This should help make the OS/2 port
cleaner, as well.
Invent a cvs-clean maintainer target that tries to get the workspace
back to the state it was in after a CVS checkout.
New language.
Incorporate "order-only" prerequisites patch. Wrote a test for it.
The test shows what might be a bug in the code; I need to look at it
more closely (anyway it doesn't behave as I expected). Also I haven't
done the docs yet.
New version of the manual, put into the doc subdir.
Enhancements: $(eval ...) and $(value ...) functions, various bug
fixes, etc. See the ChangeLog.
More to come.
