On Mac OS, in all cases use the standard compiler invocation, just being sure to include the -g option.

Absoft Fortran 90	f90 -g program.f90
GCC C	gcc -g program.c
GCC C++	g++ -g program.cxx
GCC Fortran	g77 -g program.f
IBM xlc C	xlc -g program.c
IBM xlC C++	xlC -g program.cxx
IBM xlf Fortran 77	xlf -g program.f

On Mac OS X, you can create 64-bit applications using GCC 4 by adding the -m64 command-line option.
