#	Makefile for Floating Point Preprocessor
#	For machines without floating point hardware
#	SEE FIS SELECT OPTION BELOW
#
#	Fpp is called with the -F option to 11cc, using ./fpp
#	Programs which call this must have the F library [11libF.a]
#	linked in with them {included here}
#
#	The Standard C library should be remade with the -F option, too,
#	so as not to use floating point instructions, and called
#	11libFc.a

# god: these are (I believe) the minimum basic requirements for
# using fpp.  The other files have junk like math routines
# and use an old printf.  The math routines are
# probably better than the standard libc ones, but it is better
# to use the standard atof and print.c
