That's not how any compiler works, much less DJGPP.  Each type of file
(headers, libraries, binaries) has its own separate directory in the
DJGPP installation tree.  If you preserve the directory structure when
you unzip the DJGPP zipfiles, these directories should be created
automatically.  After that, all you have to do is set the two
environment variables that DJGPP requires and you're ready to go.

Under no circumstances should you write your program in the same
directory as the system headers, nor should you copy the system headers
into your program's directory.

I assume you didn't read the file named 'v2/readme.1st' that explains
exactly how to install and use DJGPP, or that you didn't understand what
you read.  Please try again and tell us if that helps.

main() must return an integer according to the ANSI C standard. 
Declaring it as void, or omitting a 'return' statement can cause subtle
and hard to debug problems, particularly when using RHIDE.  Reference:

11.12 through 11.15.
