# End of variables for you to override.


# Variables you should change for certain systems.

# These are what you would need on HPUX:
# CFLAGS = -Wc,-Ns2000 -Wc,-Ne700 -Wc,-Np300
# If you are using the GNU assembler and linker on HPUX,
# add -I../hp-include to CFLAGS.
# -g is desirable in CFLAGS, but a compiler bug in HPUX version 5
# bites whenever tree.def, rtl.def or machmode.def is included
# (ie., on every source file).
# If you have a floating point accelerator, you might want -lsetjmp as well.
# CCLIBFLAGS = -Wc,-Ns2000 -Wc,-Ne700 -O
# HARD_PARAMS_FLAGS = -Wc,-Ns2000 -Wc,-Ne700
# INSTALL = cp
# For CCLIBFLAGS you might want to specify the switch that
# forces only 68000 instructions to be used.
# If using the GNU assembler and linker, set AR to the GNU ar program,
# wherever that is.
# To get a working alloca, you may need to get alloca.s from Emacs
# and assemble it into alloca.o rather than using alloca.c.

# On the Sequent, you may need to set CCLIBFLAG to empty.

# On the 3b1, this line may help you compile gnulib
# if you already have a prior version of gcc installed.
# CCLIBFLAGS = -B/usr/local/lib/gcc- -tp -Wp,-traditional

# On SysV from SCO, uncomment these lines as well as those for SysV in general.
# You might also want to remove limits.h from the definition of USER_H,
# since the one that comes with the system is good for POSIX.
# RANLIB = :
# CC = rcc
# OLDCC = rcc

# On a 386 running an ISC system, uncomment the following lines.
# You also need to add -D_POSIX_SOURCE to CFLAGS
# when compiling with GCC.
# INSTALL = cp
# CLIB = -lPW -lcposix

# If you are making gcc for the first time, and if you are compiling it with
# a non-gcc compiler, and if your system doesn't have a working alloca() in any
# of the standard libraries (as is true for HP/UX or Genix),
# then un-comment the following line when compiling with the system's cc:
# ALLOCA = alloca.o
# But don't do that if compiling using GCC.

# If your system has a working alloca in /lib/libPW.a,
# un-comment the following line.  Note that -lPW doesn't work on HPUX or IRIX.
# CLIB= -lPW

# On SysV R4, when compiling with PCC, you can get alloca as follows:
# CLIB = -lc /usr/ucblib/libucb.a
# -lc is needed because if libucb.a were searched before libc.a,
# you would get an incompatible stdio package that won't work.

# On the NCR Tower 32 running SVR3, says ra@intsys.no :
# Do *not* enable optimization in CFLAGS when using the native cc, because:
# a) The optimizer seems to loop when invoked with -O2.
# b) The -O1 level does stack/frame pointer optimizations that make the
#    assembler alloca in libPW.a fail, and the C alloca eats *lots* of memory.
# c) gcc will eventually be recompiled with itself, so all this doesn't matter.
# CFLAGS = -g -O0
# HARD_PARAMS_FLAGS = -O0
# CCLIBFLAGS = -O2
# CLIB = -lmalloc -lPW

# On a pyramid, you need to uncomment the following line:
# CLIB = -lc /usr/.attlib/libPW.a

# If your system's malloc() routine fails for any reason (as it does on
# certain versions of Genix), try getting the files
# malloc.c and getpagesize.h from GNU Emacs and un-comment the following line:
# MALLOC = malloc.o

# To build gcc for Apollo 68K machines you must be running at least SR10.2
# with the 6.7 version of the C compiler. Use 'apollo68' as the argument to
# config.gcc, then go into a bsd4.3 environment and use this:
# CFLAGS = -g -O -Acpu,3000 -Arun,bsd4.3 -Asys,any -Anansi $(XCFLAGS)
# CCLIBFLAGS = -O -Acpu,3000 -Arun,bsd4.3 -Asys,any -Anansi
# HARD_PARAMS_FLAGS= -Anansi
# (Says vasta@apollo.com.)
