# This is probably the correct define, to override the Makefile
# default, but using it causes more problems than it solves.
#
# Using it will cause fixincludes to try and fix some of the
# mwcc header files, which it seems to do a poor job of.  On
# the other hand, not using it will only cause the gcc version
# of limits.h to lack the header and trailer parts that are
# tacked on to it when there is a limits.h in the system header
# dir.
#
# For now it is probably better to change the rule for
# LIMITS_H_TEST to explicitly look for the BeOS limits.h.
# If the gcc limits.h is not set up to #include_next the
# BeOS limits.h, then some things will go undefined, like
# PATH_MAX.
