# This is an example INI file that can be used to set compiler options
# without the rquirement for supplying them as arguments on the command
# line, this can be coupled with progs.src.  To utilize this file there
# are two options availble, if it's named "gmqcc.ini" or "gmqcc.cfg" and
# the file exists in the directory that GMQCC is invoked from, the compiler
# will implicitally find and execute regardless.  For more freedom you may
# use -config=<file> from the command line to specify a more explicit
# directory/name.ext for the configuration file.


# These are common compiler flags usually represented via the -f prefix
# from the command line.
