# System V: 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.

# 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 and readline.c 
# will be incorrectly compiled.  The "fixincludes" script in the gcc
# distribution will fix your include files up.
