# *** User Config Section ***
# Here you can look for settings to change if the code refuses to compile
# out of the box. There are so many different systems. So many versions
# of compilers. So many different bugs. :(
#
# Select compiler
CC=gcc
#
# If cpu specific optimization fails, uncomment the next line to switch it
# off - there are some gas versions around that don't like the cpu specific
# asm instructions in dmsdos...
# CPUFLAGS=
#
# Some gnu assembler versions have a bug in the syntax for the xlat 
# instruction. This enables a workaround. It should only be needed for very
# old binutils versions. I don't know for which ones :(
# CPUFLAGS+= -DGAS_XLAT_BUG
#
# The next lines should detect SMP configuration automatically.
# Comment them out or set it manually if it fails.
ifeq ($(SMP),1)
CPUFLAGS+= -D__SMP__
endif
# 2.2.x kernels have this one...
ifeq ($(CONFIG_SMP),y)
CPUFLAGS+= -D__SMP__
endif
#
# The next lines are for libc6 and enable some compatibility hacks -
# uncomment the line with -D__FOR_LIBC6 if the code does not compile
# *** Currently not used - code should compile under libc6 without hacks
LIBC6FLAGS=
#LIBC6FLAGS= -D__FOR_LIBC6
#
# CFLAGS for dmsdos module
# note: some macro expansions require at least -O
CFLAGS= -Wstrict-prototypes -O3 -fomit-frame-pointer
CFLAGS+= $(CPUFLAGS)
#
# The next lines add some stuff automatically for people using modversions
# if they fail, comment them out and set the required flags manually
ifeq ($(CONFIG_MODVERSIONS),y)

# is different from that in /usr/src/linux you'd better edit the next line :)
