[Gm2] gm2 Cygwin port

[Gerrit P. Haase]

Hello,

currently I try to bootstrp gcc-3.3.3 including GNU Modula 2.

There are some difficulties.

Though Cygwin provides managed mounts and it is possible to use the
same name (e.g m2lex.def & M2lex.def) in the same directory it wouold
be nice to not force the user to make use of the managed mounts.

To use entirely different filenames (besides the case) would also help
to get it compiled on Windows systems without using Cygwin (MinGW).

I always use the bootstrap target to build the whole compiler
collection.

Unfortunately it fails for me with this error:

In the Makefile, at this place GCC_FOR_TARGET is used which seems to
hold a reference on ./xgcc which was aleady moved to a subdirectory
(stage2 in this case).  I guess the build order is somewhat wrong.

Can you give me a hint what and where to change?
