# -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 compiling this with CC on HPUX, you need the following line:
CLIB = alloca.o
# Get alloca.o from GNU Emacs.

# You must also change the line that uses `ranlib'.  See below.
