New Revision: 286699
URL: https://svnweb.freebsd.org/changeset/base/286699
Log:
In gcc's libcpp, stop using the INTTYPE_MAXIMUM() macro, which relies on
undefined behavior. The code used this macro to avoid problems on some
broken systems which define SSIZE_MAX incorrectly, but this is not
needed on FreeBSD, obviously.
