#
# The following values should be passed in by the invoker of the
# Makefile:
#
#	CC		C Compiler to use
#	CFLAGS32	32-bit CFLAGS
#	CFLAGS64	64-bit CFLAGS
#	CTFCONVERT	Path to ctfconvert
#	CTFMERGE	Path to ctfmerge
#	DEBUGFLAGS	The set of debug flags to use
#	BUILDDIR	Directory things should be built in
#	CHECK32		Program to check 32-bit output
#	CHECK64		Program to check 64-bit output
