# cc - wrap the IBM compiler to look sort of like a unix compiler
#      (and also to tidy up its output)
# usage: cc [opts] sourcefile
# options:
#     -g	debug
#     -O	optimize
#     -fPIC	generate shared library code
#     -Dsym	define preprocessor symbol SYM
#     -Idir	add include path
#     -c	compile only and don't link (required and assumed)
#     -v	verbose
#
# Note that the behavior of -D is limited by the ability of the shell
# to handle embedded spaces. It's meant to be only used in the style
# "-DFOO".
