Yes, it seems that wrong target underscoring is the problem here. I have
seen this problem too when moving Mamaich's toolchain into gcc4.

You should check cegcc's (http://cegcc.berlios.de) start files. They are
similar, but not the same.

There are other problems that I fixed for c++ and for binutils related
to underscoring. I have fixes (some are already in binutils mainline),
to enable the generation of correct dlls.

You will find patches for that at cegcc's file section.
I don't know if d is debuggable with gdb, but I have also improved on
gdb for
arm-wince-pe. For that you will need to get gdb from cegcc's svn.

That being said, are can try adding a
-fno-leading-underscore to TARGET_LIBGCC2_CFLAGS in
gcc/config/arm/t-wince-pe

Cheers,
