The path only tells gcc *where* to look for libraries, but it doesn't tell
it *what* libraries to scan.  You need to tell gcc to scan libgrx20.a,
like this: 

	gcc myprog.c -lgrx20

The -lgrx20 switch tells gcc to scan libgrx20.a, and LIBRARY_PATH tells 
it where should it look to find libgrx20.a (and other libraries).
