I don't think we need more at this time.  In fact, I'd even say forget 
the malloc_debug version and run only the normal combinations, with and 
without Unixy sbrk.  A combination where Make is with Unixy sbrk but GCC 
isn't might also be useful.

Didn't you say that you have 2 DJGPP installations there?

Is it true that your DJGPP environment variable is set to 
D:\dj204\djgpp.env, and that there's no cc1.exe in D:\dj204\bin?

In any case, the traceback shows explicitly what binary was running, 
including its full path; please double-check that when you run your 
tests.

Thanks again for working on this.
