Nate, Eli: 

Thanks for your detailed responses. I apologize for confusing DJGPP and
its GCC. I made several changes to my procedure and, while it is now an
easier procedure to follow the result is the same: I can compile C and
objective-c but not C++. In the interest of reducing turnaround time I
have attached both my BAT file for the complete rebuild and the Makefile
*after* my small edits as described in the BAT file. 

It looks a bit like the c++ language is not being built. I see from the
output of gcc that it is trying to use the .cc file as linker input
rather than compiling it. I haven't changed the specs file from the
binary distribution. 

It may be that <make "LANGUAGES=c c++"> isn't working, but I also tried
overriding LANGUAGES in the makefile and that didn't help either. 

It may also be a problem of setting the install targets. I took Eli's
suggestion and set $prefix and $local_prefix to $(DJDIR). However some
of the other targets, in particular libsubdir, are probably funky. The
libsubdir = $(libdir)/gcc-lib/$(target)/$(version) setting gives a
directory that does not exist. I'm not sure if it should point to a
directory in the standard DJGPP distribution. 

The following is program test.cc

#include <stdio.h>
int main() {
  printf("Hello, World!\n");
}

Here are some trace results of my attempts to get it built with C++.
