#
# Definitions of compilers and compile options for all Makefiles.
# Use GNU make.
#
# The _XOPEN_SOURCE and _XOPEN_SOURCE_EXTENDED defines are set to 1 to
# to allow certain prototypes to be included properly and indicate
# that the program is to work with the X/Open XPG4v2 (SUS)
# standard. Specifically, this wasy getopt() will compile and work
# nicely with no warnings on Solaris, and also allow the use of
# strcasecmp() and strdup() with no warnings. 
#
# set MODE=DEBUG to build with debugging and profiling on. Otherwise
# default is to build with optimizations on and no debug or profile.
