This is actually not the correct way to link the library - you should use the
-l compiler option, i.e.

gcc -Wall -g -O -o myprog.exe myprog.c -lgrx20

The stuff at the beginning is useful to add, too (look in the gcc docs for
explanations).  :)

The path tells gcc where to look *for* libraries that you instruct it to link
with the -l switch.  It doesn't instruct the linker to look *in* all those
libraries,
though - that would seriously slow it down.  The only files linked in
automatically are libc.a, libgcc.a, and crt0.o - you yourself must specify
any others that you need.  (Exception:  'gxx' automatically links the C++
libraries when run, but it is in effect just a fancy wrapper for 'gcc'.)
