# 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 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.
#
# NOTE: On some systems, the library path does not include the location
#	of the X11 libraries.  You might need to use a -L/path/to/X11/lib/dir
#	in order to compile with these libs.
#
#CFLAGS=-O -Xa

#CFLAGS= -ansi -L/usr/X11R6/lib

# ANSI compiler
#
# Set CC to the name of your ANSI compiler.
#
# Some entries seem to need gcc.  If you have gcc, set
# both CC and MAY_NEED_GCC to gcc.
#
# If you do not have gcc, set CC to the name of your ANSI compiler, and
# set MAY_NEED_GCC to either ${CC} (and hope for the best) or to just :
# to disable such programs.
