Error building cross compiler from mainline




   I'm trying to build a Mac OS X -> Win32 (MinGW) cross compiler using 
the latest CVS mainline sources (and I want to be using DLLs instead of 
static libraries for stuff like libobjc).  I've previously done this 
with the 2.95.2 based compiler from www.mingw.org (except for the DLL 
part), but the MinGW folks claim that GCC mainline should mostly work 
now.

   I installed a recent binutils snapshot with the target 
'i386-mingw32msvc' w/o any trouble.

   Then, when I try to configure and build GCC, I did:

../../source/gcc/gcc/configure -v 
--prefix=/Users/Shared/$USER/Build/MinGW --target=i386-mingw32msvc 
--with-gnu-as --with-gnu-ld --disable-multilib --enable-shared 
--disable-static --enable-languages="objc"
make CC="cc -no-cpp-precomp"

   This built along for a while and then when building libobjc I got 
stuff like the following:

   Presumably this stems from the truly horrible section of libtool:


archive_expsym_cmds="if test \\"x\\`head -1 \$export_symbols\\`\\" = 
xEXPORTS; then
         cp \$export_symbols \$output_objdir/\$soname-def;
       else
         echo EXPORTS > \$output_objdir/\$soname-def;
         _lt_hint=1;
         cat \$export_symbols | while read symbol; do
          set dummy \\$symbol;
          case \\[\$]# in
            2) echo \\"   \\[\$]2 @ \\$_lt_hint ; \\" >>

            *) echo \\"     \\[\$]2 @ \\$_lt_hint \\[\$]3 ; \\" >> 
\$output_objdir/\$soname-def;;
          esac;
          _lt_hint=\\`expr 1 + \\$_lt_hint\\`;
         done;
       fi~

   Does anyone have any advise about what I may have done wrong?
