This commits a number of changes from Earnie Boyd that allows GNU make
to build for MINGW32 systems. Only missing from this commit are the
changes to configure.in etc.; I'm waiting for Earnie to sign papers for
those new files.
Also not here is any README.mingw32 etc. which would explain how to use
this port.
Fixed problems with the dist target (adding missing files).
Workaround for a bug in gettext 0.12.1 po/Makefile.in.in where distclean
wasn't cleaning everything, which caused distcheck to fail.
Implemented enhancement #1391: allow "export" in target-specific
variable definitions.
Change the Info name of the "Automatic" node to "Automatic Variables".
Add text clarifying the scope of automatic variables to that section.
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.
