This reverts commit 2a3721bf98 because it
requires further changes in bakefile itself to really work under Mac, where
the build would be broken as soon as configure would be regenerated (which was
forgotten by that commit due to another error, and so the two errors finally
cancelled out).
Use the macro versions from 2.24.29 and 3.18.8 (latest available in Debian for
GTK+ 2 and 3 respectively) to fix the detection of pkg-config which was
incorrect in the old gtk-2.0.m4.
Closes#17027.
Make it simpler to enable C++11 support when building wxWidgets, in particular
take care of using the correct standard library under OS X in this case.
Notice that currently we still build the library using C++98 if no C++11
compiler is available, even with this option. We may want to change this to
give an error in such case later instead.
Also skip the check for <type_traits> in configure when C++11 is used, we know
that it's available in this case, so don't waste time checking for it (there
are probably several more checks that could be skipped in C++11 mode too...).
It seems like it was never really needed as we always delete the archive
before creating it anyhow and there is no advantage in "updating" it if it
doesn't exist. Worse, with recent ar versions (like the one from binutils 2.25
in Debian Sid), using "u" results in a somewhat unclear warning
ar: `u' modifier ignored since `D' is the default (see `U')
so just get rid of it to avoid the warning.
Visibility support for Clang was disabled in 7198c33 because of linking
errors when building shared libraries, related to non-inline methods in
exported template classes.
The last Clang version to have these problems is version "4.1
(tags/Apple/clang-421.11.66)" as part of Xcode 4.5.2, and the next
release fixes them (version "4.2 (clang-425.0.24)", Xcode 4.6). Check
for the Clang version and only disable visibility support when compiling
with Apple Clang < 4.2.
Note that Apple Clang 4.2 is based on official Clang 3.2 so also check
for that version in case of non-Apple builds. The only official Clang
that has been tested successfully is 3.4 which worked fine with
visibility. Other versions that were tried (3.1 and 3.2) segfault while
compiling wx.
This port is not used and is not being worked on, so remove it to reduce the
amount of the code which needs to be updated for every global change.
Also remove tests for VisualAge compiler which isn't used since ages.

Assigning __sync_sub_and_fetch() result to an unused variable can result in it
being optimized away and the function support is then not really tested for,
see #4542. So do make sure this variable is kept by making it volatile.
Closes#15555.

This keyword is not expanded by Git which means it's not replaced with the
correct revision value in the releases made using git-based scripts and it's
confusing to have lines with unexpanded "$Id$" in the released files. As
expanding them with Git is not that simple (it could be done with git archive
and export-subst attribute) and there are not many benefits in having them in
the first place, just remove all these lines.
If nothing else, this will make an eventual transition to Git simpler.
Closes#14487.

Even Clang++ shipped with Xcode 4.1 still can't handle visibility
of non-inline methods in exported template classes if the default
visibility is 'hidden'.
Disable visibility support for Clang for now, we'll revisit it in the future.

Update configure and bakefile.m4 for the new version too.
Also add the missing makefiles and projects for the XTI sample.

Use AC_REQUIRE() instead of directly using a macro, the latter doesn't work
with autoconf 2.65.
This is a backport of r1337 from bakefile svn to allow people to use autoconf
2.65 immediately and will become unnecessary when we update to the next
bakefile version.

Copied bakefile.m4 from bakefile svn and regenerated configure using it.
This should have been done in r62308 but was forgotten. Notice that we can't
use bakefile 0.2.6 any more without reverting this change!
