as defined in Mk/bsd.default-versions.mk which has moved from GCC 8.3
to GCC 9.1 under most circumstances now after revision 507371.
This includes ports
- with USE_GCC=yes or USE_GCC=any,
- with USES=fortran,
- using Mk/bsd.octave.mk which in turn features USES=fortran, and
- with USES=compiler specifying openmp, nestedfct, c11, c++0x, c++11-lang,
c++11-lib, c++14-lang, c++17-lang, or gcc-c++11-lib
plus, everything INDEX-11 shows with a dependency on lang/gcc9 now.

From the changelog:
* Support for UTF-8 in file names and comments (Denis Zavorotnyy)
* get/setOsCode(), get/setDefaultOsCode()
* Fixed Z_STREAM_END handling in QuaZioDevic
a symbol matches multiple clauses the last one takes precedence. If the
catch-all is last it captures everything. In the case of Qt5 libraries
this caused all symbols to have a Qt_5 label while some should have
Qt_5_PRIVATE_API. This only affects lld because GNU ld always gives the
catch-all lowest priority.
Older versions of Qt5Webengine exported some memory allocation symbols from
the bundled Chromium. Version 5.9 stopped exporting these [1] but the
symbols were kept as weak wrappers for the standard allocation functions to
maintain binary compatibility. [2][3] The problem is that the call to the
standard function in these weak wrappers is only resolved to the standard
function if there's a call to this standard function in other parts of
Qt5Webengine, because only then is there a non-weak symbol that takes
precedence over the weak one. If there's no such non-weak symbol the call
in the weak wrapper resolves to the weak wrapper itself creating an infinite
call loop that overflows the stack and causes a crash. Some of the
allocation functions are variants of C++ new and delete and it probably
depends on the compiler whether these variants are used in other parts of
Qt5Webengine.
Remove the weak wrappers (make them Linux specific). This isn't binary
compatible but we are already breaking that with the changes to the symbol
versions.

Change x11/xorgproto to become a build time dependency when added to
USE_XORG. Change the dependency to be on the port, rather than a file the
port installs.
Fix fallout.
Bump portrevision on depending ports.

According to upstream, this is the last planned Qt4 release.
A list of changes since 4.8.6 can be found here:
<http://download.qt.io/official_releases/qt/4.8/4.8.7/changes-4.8.7>
Porting notes and changes:
- Remove several patches that have been upstreamed.
- Make Uses/qmake.mk pass the contents of LIBS to the qmake environment. [1]
- Repurpose devel/qt4/files/extrapatch-src-corelib-global-qglobal.h now the
original patch is part of the release (curiously enough, the original
patch was never actually used, as the ?= assignment in r362837 after
r362770 was never possible).
This works around the way compiler support for C++11 features is detected
in Qt 4.8.7: while it originally only uses the compiler to determine if
something is supported or not, the initializer lists feature also depends
on the C++ standard library being used. It's a problem in FreeBSD 9.x,
where USES=compiler:c++0x or USES=compiler:c++11-lang means we will use
clang to build a port but use libstdc++ from base (GCC 4.2). The latter
obviously does not support initializer lists, and the build fails because
Qt tries to include headers that do not exist (<initializer_list>).
Since detecting libstdc++'s version is not trivial (we need to include a
non-lightweight header like cstdio and then check for __GLIBCXX__), we
just enable Q_COMPILER_INITIALIZER_LISTS support only when libc++ is used
(there should be no reason for someone to be using clang with GCC 4.8's
libstdc++, for example).
x11/kdelibs4's FindQt4.cmake had to include a backported change from the
upstream FindQt4.cmake in CMake itself to use a C++ compiler to detect
flags like Q_WS_X11, otherwise the inclusion of <ciso646> in qglobal.h
makes the build fail.
This patch contains changes by me, makc@ and alonso@.
