This includes the merger of the GCC wide-int development branch and fails
to build with clang on 10-i386 and 10-amd64 with two rather different
failure modes (stage 2/3 comparison failure and simple compilation error,
respectively) so for the time being require building with GCC while I am
working with upstream.
Since FreeBSD 8.4 and FreeBSD 9.1 make(1) do support :tu and :tl as a
replacement for :U and :L (which has been marked as deprecated)
bmake which is the default on FreeBSD 10+ only support by default
:tu/:tl a hack has been added at the time to support :U and :L to ease
migration. This hack is now not necessary anymore
Note that this makes the ports tree incompatible with make(1) from
FreeBSD 8.3 or earlier
With hat: portmgr
GCC 4.9 development and is feature equivalent at this point.
The coming months, during stage 1 of GCC developemtn, there will be
many invasive and partially destablizing changes. Any outfall will
be addressed in the second half of the release cylce. Until then,
use at your own risk and file any bugs upstream.
