Return to Makefile.in CVS log

Up to [gforth] / gforth / engine

various changes in configure.in and the Makefile.in's:
   symlinks kernel.fi and arch/machine eliminated
   utilize some automake stuff (e.g., @VERSION@ and @lispdir@)
   eliminated engine/version.h
   eliminated replace.a; gforth[-ditc] is now built by engine/Makefile
   getopt_long replacement is now donw through LIBOBJS, like everything else
automake-induced changes in acconfig.h; added acinclude.m4 and AUTHORS.
aclocal.m4 is now generated (it's still in CVS because there's not yet a
	make rule for it).
made gforthmi more conformant with GNU standards (--version etc.).
prim: fixed portability bug (RTLD_GLOBAL does not exist everywhere)
arch/power/machine.h: refined cache flush code
doc/gforth.ds now uses @VERSION{} (but we need to generate version.texi)
	documented new buffering behaviour
