Log message:
Remove gcc45,46,47 and libs as discussed in pkgsrc-users
GCC_REQD for these versions now resolves to gcc48 due to a previous commit.

Please file a bug report if you are having trouble with GCC 4.8.

Log message:
gcc47: don't use PCH for libstdc++ on gcc5, it causes hangs during configure.
limited to gcc5 because others do not seem to run into the same issues, to
avoid a regression for them.

disable libssp on netbsd - it conflicts with native libssp
(related: PR pkg/47213)

Use a more sane specfile for netbsd, linking against libc when building
shared.

bump gcc47 PKGREVISION
bump gcc47-libs PKGREVISION further than gcc47

Log message:
Bump lang/gcc47-libs PKGREVISION to stay ahead of lang/gcc47.

Log message:
Remove mk/find-prefix.mk usage from the lang category.

The find-prefix infrastructure was required in a pkgviews world where
packages installed from pkgsrc could have different installation
prefixes, and this was a way for a dependency prefix to be determined.

Now that pkgviews has been removed there is no longer any need for the
overhead of this infrastructure.  Instead we use BUILDLINK_PREFIX.pkg
for dependencies pulled in via buildlink, or LOCALBASE/PREFIX where the
dependency is coming from pkgsrc.

Provides a reasonable performance win due to the reduction of `pkg_info
-qp` calls, some of which were redundant anyway as they were duplicating
the same information provided by BUILDLINK_PREFIX.pkg.

Log message:
Disable CHECK_SHLIBS for the GCC library packages.  The libraries will
find their parent GCC package libraries first in RPATH at install time
but will correctly resolve to their own copies at runtime thanks to the
additional paths encoded at build time.  Fixes CHECK_WRKREF builds.

Log message:
Strip libgo from the package, it is very large and useless in this context.

Ride previous PKGREVISION bump.

Log message:
Update to 4.7.4

* Reset gcc47-libs' PKGREVISION to 1

Changelog:
* Bugfixes.

Log message:
Support the override libgcc specs for the cwrappers case.
