Fwd: GCC 3.1 linux-to-mingw32 near success but still some questions remain ;-)

Sorry, I haven't installed any patches(I haven't really looked at whether 
such patches exist, either)
What's the reason that one would have to apply "external" patches to the gcc 
source tree?

So no easy configure; make; make install on every platform just yet I guess...

For now, I've dropped the idea of building native mingw tools, because I have 
discovered a severe problem with my cross compiler when trying to 
cross-compile the latest wxWindows sources from CVS:

i686-pc-mingw32-c++ -shared 
-Wl,--out-implib,lib/libwx_msw-2.3-i686-pc-mingw32.dll.a -o 
lib/libwx_msw-2.3-i686-pc-mingw32.dll  accel.o app.o bitmap.o bmpbuttn.o 

<...tons of object files...>

inftrees.o infcodes.o infutil.o inffast.o automtn.o dataobj.o dropsrc.o 
droptgt.o oleutils.o uuid.o -Wl,--subsystem,windows -mwindows  -lm -lrpcrt4 
-loleaut32 -lole32 -luuid -lwinspool -lwinmm -lshell32 -lcomctl32 -lctl3d32 
-ladvapi32 -lwsock32
Creating library file: lib/libwx_msw-2.3-i686-pc-mingw32.dll.a
i686-pc-mingw32-c++: Internal error: Segmentation fault (program ld)
Please submit a full bug report.
See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.
make: *** [lib/libwx_msw-2.3-i686-pc-mingw32.dll] Error 1

Obviously, there's not much I can do about that, except make sure I have 
enough free disk space (600MB) and memory (384 MB)

Would ld give a more "informative"  error message if free memory or so was 
the problem?

Or, in other words, does this look like a very severe (misbuild?) problem?
