We have recommended against USE_GCC=any for a while, and as of more
recently it was completely equivalent to USE_GCC=yes.
With (ancient versions of) GCC hardly available in the base system
of FreeBSD systems at this point, there's unlikely to be a use case
to reintroduce it, so remove the few remaining traces.

Now that GCC 11.1 has been released and lang/gcc11 is in place,
have USE_GCC=11 use that instead of lang/gcc11-devel.
In addition add support for USE_GCC=12 which uses lang/gcc12-devel
(still in early development, not recommended for production use).
USE_GCC=any was introduced to leverage the old version of GCC 4.2
installed as /usr/bin/gcc on some systems. That has increasingly
not been present any longer (not on i386 and amd64 since 12.x and
optionally 11.x, not even on the ppcdevref system according to
linimon@) and hardly anyone actually has been testing ports in
this scenario.
So, finally stop using /usr/bin/gcc (and /usr/bin/gc++ and
/usr/bin/gcpp) even if present.
This makes USE_GCC=any just another way of spelling USE_GCC=yes
before we finally de-orbit it.
Discussed with: mat, linimon, pkubaj
runtimes or GCC at runtime are not required.
Introduce an optional argument for USE_GCC that indicates GCC is
only required at build time.
Examples for the new syntax are USE_GCC=yes:build, USE_GCC=9:build,
or USE_GCC=11+:build.

of GCC to use based on the specification of USE_GCC.
This is based on the observation that we now only have a single version
of GCC in base, namely GCC 4.2, which is not in ports any longer. And
we limit our choice to either the specific version requested or the
default version of GCC in the ports tree; i.e., we no longer consider
an installed port of any version in between (which is a fringe case
extremely few, if any, users would have experienced, and then only
outside a clean build environment in any case).
Streamline some debugging output accordingly.
Overall this removes some 25 lines of largely complex logic.
dependency on GCC 6 in the Ports Collection is gone, so we can remove
support for USE_GCC=6 and USE_GCC=6+. [1]
This does not remove lang/gcc6 yet, but helps avoid new dependencies,
and GCC 6 has been unmaintained upstream for more than a year.
On the way update two examples to use more current versions of GCC.

This does not remove lang/gcc5 as such, but helps avoid new dependencies

and consequently many of the USES=compiler flavors use the canonical
version of GCC as defined in Mk/bsd.default-versions.mk as well as
the lang/gcc port
With the "new" setup starting with GCC 5 where I have introduced
lang/gcc5-devel for regular snapshots and lang/gcc5 for releases,
and similarly for GCC 6 and onward, we can now leverage lang/gcc5
(and later) for most of the role that lang/gcc used to play -- and
indeed as of today lang/gcc and lang/gcc5 are nearly identical
short of symlinks for gcc, g++, and gfortran binaries that the
former provides.
So now use lang/gcc5 instead of lang/gcc whenever requested via the
USE_GCC framework directly or indirectly.
This is similar to how the python ports work, for example, and it
allows simplifications in Mk/bsd.gcc.mk and Mk/Uses/fortran.mk and
dropping LANG_GCC_IS from Mk/bsd.default-versions.mk. As a next
step lang/gcc is going to become a "hull" essentially only providing
those symlinks and requiring lang/gcc5 (or whatever has been set as
default in Mk/bsd.default-versions.mk).
The variable defined in it are now always available after including
bsd.port.pre.mk.

GCC 4.6.4 to GCC 4.7.3. This entails updating the lang/gcc port as
well as changing the default in Mk/bsd.default-versions.mk.
This adds powerpc64 as a supported architecture (and removes ia64,
though it can be supported by manually installing lang/gcc48).
New binaries %%GNU_HOST%%-gcc-ar47, %%GNU_HOST%%-gcc-nm47, and
%%GNU_HOST%%-gcc-ranlib47 are provided to support link-time
optimization (LTO) which scales significantly better.
And it adds support for indirect functions (IFUNCS), experimental
support for transactional memory in the compiler as well as a supporting
run-time library called libitm, a new string length optimization pass,
and support for atomic operations specifying the C++11/C11 memory model.
Version 3.1 of the OpenMP specification is now supported for the C,
C++, and Fortran compilers.
GCC accepts the options -std=c11 and -std=gnu11 for the C11 revision
of the ISO C standard which inlcude support for unicode strings,
nonreturning functions (_Noreturn and <stdnoreturn.h>), alignment
support (_Alignas, _Alignof, max_align_t, <stdalign.h>), and a
__builtin_complex built-in function.
The C++ frontend now accepts the -std=c++11, -std=gnu++11, and
-Wc++11-compat options and implements many C++11 features of the
language including extended friends syntax, explicit override
control, non-static data member initializers, user-defined literals,
alias declarations, delegating constructors, atomic classes, and more.
The C++ standard library and Fortran frontend have received many
improvements. See http://gcc.gnu.org/gcc-4.7/changes.html for an
extense list of changes; http://gcc.gnu.org/gcc-4.7/porting_to.html
