# flags for ANSI compiles
#
# NOTE: Some ANSI compilers make use of -Xa to turn on ANSI mode,
#	others such as gcc may want -ansi, others (Compaq Tru64 Unix)
#       want -std1, and others may want nothing at all.
#       Adjust the CFLAGS line as needed.
#
# NOTE: Some compilers cannot optimize, or optimize some entries
#	incorrectly.  You might want to turn on -O to see if your
#	compiler can handle them.
