# On HPUX, you need to add -Ihp-include to CFLAGS.
# The headers in the directory hp-include override system headers
# and tell GDB to use BSD executable file format.
# You must also define REGEX & REGEX1 below and ALLOCA & ALLOCA1 (get
# alloca.c from the emacs distribution) to the CLIBS.
# If you compile GDB with GCC on HPUX, you must make sure that the "nm" used
# in "munch" is GNU's nm.  This is because gcc uses a different .o
# file format than the native HPUX compiler.

# On USG (System V) machines, you must make sure to setup REGEX &
# REGEX1 to point at regex.o and use the USG version of CLIBS.  
# If your system has a broken alloca() -- most do -- then get
# alloca.c from the GNU Emacs distribution and set ALLOCA & ALLOCA1.
# Also, if you compile gdb with a compiler which uses the coff
# encapsulation feature (this is a function of the compiler used, NOT
# of the m-?.h file selected by config.gdb), you must make sure that
# the GNU nm is the one that is used by munch.

# On Sunos 4.0 machines, make sure to compile *without* shared
# libraries if you want to run gdb on itself.  Make sure to compile
# any program on which you want to run gdb without shared libraries.

# If you are compiling with GCC, make sure that either 1) You use the
# -traditional flag, or 2) You have the fixed include files where GCC
# can reach them.  Otherwise the ioctl calls in inflow.c will be
# incorrectly compiled.  The "fixincludes" script in the gcc
# distribution will probably fix your include files up.
