I'm having trouble with the -VCSD option in Mark Williams C, version 3.05.

The problem was discovered trying to debug a complex GEM application,
but can be demo'd with some very simple files:

foo.h - local include file that defines global variable "foo"
mod1.c - source module which #includes foo.h
main.c - another source module which #includes foo.h

The program compiles and runs when I compile with "cc mod1.c main.c".

However, with "cc -VCSD mod1.c main.c" there will be a complaint
similar to:

  "ld: foo redefined in main.c"

The resulting object code does not run (hangs, warm-boot required!)
and CSD is all confused if I try to use it.

If I compile only one of the source modules with -VCSD the link is
okay and I can run CSD (but this means I can debug only one module at
a time, whoopee).

This doesn't happen when a header file like stdio.h is included in
both files.

So, somehow the extra debug stuff generated by -VCSD causes trouble in
the linker. Does anyone know of a workaround? (Yes, I'll be writing
MWC soon!).
