windres on mingw32 and cygwin

[Jason Curl]

Hello,

My next woe when porting over to libtool-2.x. It looks like the 
compilation phase of libtool has changed for resources. The shared 
library works, but the static library build on mingw32/cygwin no longer 
works.

Not sure what I did to completely break it.

Hope somebody can help, the libtool manual contains very little about 
windows dlls.

The relevant output of the build is:
/bin/sh ../../libtool   --tag=RC --mode=compile windres  rsrc.rc -o rsrc.lo
libtool: compile:  windres rsrc.rc  -o .libs/rsrc.o
libtool: compile:  windres rsrc.rc >/dev/null 2>&1
/bin/sh ../../libtool --tag=CC   --mode=link gcc -mno-cygwin  -g -O2 
-no-undefined -version-info 1:0:0 -Wl,--add-stdcall-alias  -o libwin.la 
-rpath /usr/local/lib version.lo libmain.lo rsrc.lo

-Xlinker .libs/libwin.dll.a

It seems like it's put in .libs and not in the same directory as the 
source, and this is why it can't link.

I currently do:

configure.ac
LT_INIT([win32-dll])
LT_LANG([Windows Resource])
AM_CONDITIONAL([HAVE_WINDRES], [test x$ac_cv_prog_ac_ct_RC != x])
if test x$ac_cv_c_compiler_gnu = xyes; then
  case "$host_os" in
     mingw* | cygwin*)
        SHLIB_VERSION_ARG="-Wl,--add-stdcall-alias"
        ;;
     *)
        ;;
  esac
fi
AC_SUBST(SHLIB_VERSION_ARG)
WINLIB_VERSION_INFO="1:0:0"
AC_SUBST(WINLIB_VERSION_INFO)


Makefile.am
FILES = main.c
if HAVE_WINDRES
FILES += rsrc.rc
endif

.rc.lo:
 $(LIBTOOL) $(AM_LIBTOOLFLAGS) $(LIBTOOLFLAGS) --tag=RC --mode=compile 
$(RC) $(RCFLAGS) $< -o $@

libwin_la_LDFLAGS = -no-undefined -version-info @WINLIB_VERSION_INFO@ 
@SHLIB_VERSION_ARG@
