Don't build tex2rtf and HelpGen utils in non-GUI buildbot builds.

Both of those are obsolete and don't exist in 2.9 any longer.

Don't use wxCriticalSection in wxWakeUpPipeMT if wxUSE_THREADS==0.

In fact, don't define wxWakeUpPipeMT class at all when not using threads.

Fix crash in docview code if view initialization failed.

The change of r71371 resulted in using the already destroyed (implicitly, done
as part of destroying the wxView that failed to initialize) wxDocument in
wxScopeGuard destructor.

Avoid this and make the old (i.e. pre-r71371) code exception safe while
keeping its semantics exactly, i.e. only delete all views if the document
still exists.

Also add a comment explaining what's going on here because the ownership rules
in docview code are frankly crazy.

Make wxMSW wxSpinCtrl "not enough space" messages more helpful.

And also less annoying: remove the messages from DoMoveWindow() which could be
given during resizing but not necessarily corresponded to the final control
size.

And give more details about which control is not being given enough space when
a too small size is given in the ctor.

Disable wxUSE_ENH_METAFILE for wxGTK builds.

This can happen to be defined in wxGTK builds under Windows.

Closes #15332.

Fix error checking in wxFileSystemWatcher::Remove() under OS X.

The boolean return value was compared with -1 which was always false.

Suppress harmless clang 3.3 warning about unused wxMessageOutputBest field.

Clang detects that a class member is unused (under non-Windows systems) which
is quite impressive but not really useful in this particular case, so suppress
this warning by "using" it.

Fix harmless Clang warning about an unused function.

GlobalOnAnotherEvent() is not used in normal testing.

Fix harmless Clang warning about unused class member in a test.

The m_i field is only used in the currently commented out debugging messages,
suppress a warning about it being unused.

Fix totally broken LocaleSetter class in the test suite.

It was based on a completely erroneous assumption that setlocale() returns the
locale that had been previously active when it actually returns the newly set
locale.

This fixes unit test failures in StringTestCase under OS X, as the locale
wasn't correctly restored by DateTimeTestCase that used this class.

Don't test for wide character functions in configure under OS X.

The tests for these functions may succeed on the system we're running under
but the functions may not be actually available on the system the application
is going to run under (if it's < 10.7).

So use our own replacements for these functions unless 10.7 was explicitly
chosen as the minimal possible version.

An alternative solution could have been to use weak linking but this is more
difficult and there is no real gain (performance would need to be measured
first).

Support using GetTextExtent() with empty string to get descent in wxOSX.

Allow measuring the descent and external leading of an empty string by
measuring just a space instead in wxOSX. This makes the behaviour more
consistent with wxMSW and makes the unit test added in r74464 pass under OS X
too.

Don't use images in wxToolBar with wxTB_NOICONS in wxOSX.

This results in asserts when adding items without bitmaps, but this should be
allowed when using wxTB_NOICONS.
