compiling with gmp not working

[Ankit Singla]

I tried installing gmp using the cygwin setup file, and it worked fine. 
The problem is, I can't use it. When I configure openCOBOL, it returns 
with an error saying gmp.h doesn't exist. The following file:

#include <stdio.h>
#include <gmp.h>

int main()
{
  return 0;
}

compiles as follows:
Ankit Singla@ankit /home/testNoSpace/open-cobol-0.33
$ gcc test.c
test.c:2:17: gmp.h: No such file or directory

What's odd is that gmp.h exists in my /usr/include directory, along with 
stdio.h. I also have libgmp dlls installed. Ideas?
