Unless you disable the built-in DJGPP command-line globbing in your
program (which you don't appear to have done), the command line will
already be globbed by the time you begin using arguments to main(). 
Therefore, glob() is passed the name of the first file instead of the
wildcard, and obviously returns just that one filename.

To disable automatic command-line globbing, you should #include <crt0.h>
and write a version of char ** __crt0_glob_function( char * ) (q.v.)
that does nothing except return NULL.  You can also get the same effect
by enclosing the wildcard argument to your program in double quotes:

   program "*.*"

However, the former is probably more intuitive.

BTW, if all you want to do is retrieve wildcards from the command line,
then you are better off letting the automatic globbing code do it for
you.
