The last 2.95.2 version of gcc was -9.

The current cygwin version of gcc is actually 2.95.3-1.  2.95.3-2 is a
"testing release".  There are no bug fixes in this version beyond
reapplied patches from Mumit Khan that were in the 2.95.2 releases and
my changes in cygwin.h for getting -mno-cygwin to work better.

There are additions in cccp.c, though, so the line numbers won't match.
I haven't added an abort, though.

Here are the lines in question:

  /* Scan thru the replacement list, ignoring comments and quoted
     strings, picking up on the macro calls.  It does a linear search
     thru the arg list on every potential symbol.  Profiling might say
     that something smarter should happen.  */

  if (end < buf)
    abort ();	<<<---HERE

This is in collect_expansion ().

I wonder if this is a #!!&# CRLF problem.
