Hmmmm.... the *assembler* appears to be grumbling about its input. I'd 
suspect that you have a mangled DJGPP installation. You may be better 
asking on the DJGPP mailing list.

Aside: Wouldn't it have been better to install DJGPP in c:\djgpp????

1. You allegedly have a 6-line test program. What is this example_wrap.c 
that has 112 lines (or more) in it?
2. What was the full compiler command line?
3. What are you doing with DJGPP? Are you attempting to make an MS-DOS 
port of Python?
4. Have you successfully compiled linked and executed anything with this 
installation of DJGPP? Does the standard "Hello, world!" program work? 
5. Have you tried compiling (not linking) this:

#include "Python.h"
void dummy() {}
