I haven't done it under gnuwin32, but I have done it under Solaris2
and Linux... You need to get a libgcc.a that is compiled with the
-fPIC/-fpic flag to allow linking in with a shared object (libgcc.a
contains a lot of support routines for gcc...)

I just did it by editing the gcc makefile (added -fPIC to CCLIBFLAGS
and LIBGCC2_CFLAGS).

You can then either make a libgcc.so (I assume libgcc.dll for
gnuwin32), or link the dynamically loaded routines with this new
libgcc.a).

I don't know how applicable it is to the gnuwin32 and .dlls, but I
suspect it is a similar problem.

Hope this helps,
 Andrew.
