These files are processed by aclocal (GNU Automake) to create
../aclocal.m4.  Beware that they are shared by several packages (in
other words: keep them backward compatible).

 debug.m4        support for the --disable-debug option
 doccheck.m4     check tools used to generate the documentation
 gccwarn.m4      turn on lot's of GCC warnings
 palmcheck.m4    check for compiler tools, tweaked for PalmOS
 palmdefault.m4  fudge Autoconf internals have $host default to m68k-palmos
