#
# Step 1: Choose the compile flags to use.
#
CFLAGS=-O3 -m486 -fno-strength-reduce
# CFLAGS= -O2

#
# Step 2: Choose where the binaries will be install
#
# Select a value for PREFIX.
#
# The support files will go in ${PREFIX}/lib/gcc-lib/i386-msdos-go32.
# The binaries will go in ${PREFIX}/bin/dos-${program} e.g.
#    ${PREFIX}/bin/dos-gcc, ${PREFIX}/bin/dos-stubedit, etc.
#
PREFIX=/usr/home/cgjks1/test


#
# Step 3: Tell me where to find the source code for gcc and binutils.
#
# This package has been tested with GCC 2.7.2 and BINTUILS 2.7.
# It make not work with later or earlier versions. 
#
# If you untar both gcc-2.7.2.tar.gz and binutils-2.7.tar.gz in the
# current directory then use the following paths.
#
GCCDIR=		./gcc-2.7.2
BINUTILSDIR=	./binutils-2.7


#
# Step 4: GCC version
#
# Which version of gcc are you using (it effects a path somewhere).
#
GCCVER=		2.7.2


#
# Step 4: Extra configure arguments for gcc and binutils.
#
# The extra arguments to give to ./configure when building gcc and
# binutils.
#
# In most cases there will be no extra arguments.  However, the current
# GNU tools don't recognise i686 as a processor and so on i686, Linux
# machines use "--host=i486-elf-linux" (which is recognised).
#
# Please refer to documentation in the gcc and the binutils directories.
#
EXTRA= --host=i486-elf-linux
#EXTRA=


#
# Step 5: Choose a compiler
#
# gcc and binutils will choose a compiler in their configure scripts.
# The compiler defined here will be used to compile two programs in
# the DJGPP package.
#
CC=gcc


#
# You should not change anything below this line
#
