This clearly shows that you are running the Cygnus port of GCC, not
the DJGPP port.  Is that what you want?  If so, the most probable
cause of your grief is that the way DJGPP passes long command lines to
child programs is incompatible with what the Cygnus port expects, and
so cpp gets a truncated command line.

If you need to use the Cygnus tools, I suggest you switch to the NT
port of Emacs (ftp://ftp.cs.washington.edu/pub/ntemacs/latest/i386/).
