# 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).
# CCLIBFLAGS = -Wc,-Ns2000 -Wc,-Ne700
# For CCLIBFLAGS you might want to specify the switch that
# forces only 68000 instructions to be used.

# 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 get alloca.c from GNU Emacs and un-comment the following line:
# ALLOCA = alloca.o

# If your system has alloca() in /lib/libPW.a, un-comment the following line:
# CLIB= -lPW

# 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

# If you are running GCC on an Apollo (SR10.x),
# go into a Berkeley environment and use this:
# CFLAGS = -g -A nansi -A cpu,3000 -A runtype,bsd4.3 -A systype,any -DSHORT_ENUM_BUG
# (Says vasta@apollo.com.)
