New Revision: 198344
URL: http://svn.freebsd.org/changeset/base/198344
Log:
Change gcc to assume a default machine architecture of 486 instead of 386
on "i386". Doing it in the compiler is deemed to be less fragile then
attempting to provide a default -march setting via bsd.cpu.mk. FreeBSD
itself has not supported plain 386 CPUs since 5.x.
