Recently I use Libtool CVS to compile M4 CVS in mingw/msys.I have
configureed M4 like this:
../m4/configure -C --prefix=/usr --disable-nls --disable-shared
When I make it and get these message:
/bin/sh ./libtool --tag=CC --mode=link gcc -O2 -no-undefined
-export-dynamic -dlpreopen force -dlpreopen modules/m4.la -dlpreopen
modules/traditional.la -dlpreopen modules/gnu.la -o src/m4.exe

I trace into libtool, and found it is because of $global_symbol_pipe
which is always empty. I don't konw where I am wrong. In file libtool
(exactly speaking, it should be ltmain.sh or ltmain.m4sh) I change those:
if test -n "$dlfiles$dlprefiles" || test "$dlself" != no; then
if test -n "$NM" && test -n "$global_symbol_pipe"; then
my_dlsyms="${my_outputname}S.c"
else
func_error "not configured to extract global symbols from dlpreopened
files"
fi
fi
into these:
if test -n "$dlfiles$dlprefiles" || test "$dlself" != no; then
if test -n "$NM" ; then
my_dlsyms="${my_outputname}S.c"
if test -n "$global_symbol_pipe" ; then
func_warning "not configured to extract global symbols from
dlpreopened files"
fi
fi
fi
Now I can make M4 sucessfully. Maybe I should to do more tests.
