Correct bug with returning 0 for non-empty input from wxConvAuto::ToWChar().
Since the changes of r63064 we could return 0 when asked to convert a
non-empty buffer containing only a BOM. This confused the logic in
wxTextInputStream::NextChar() and was generally unexpected so now return
wxCONV_FAILED in this case.

Check the result of ToWChar() call in wxTextInputStream::NextChar() better.
The logic in this function depends on ToWChar() working correctly so check
that it doesn't return obviously wrong results, e.g. 0 output length for
non-empty input. This was mostly done to detect the problem in wxConvAuto
currently but it could also be useful with user-defined conversions and
shouldn't have a big performance effect on wxTextInputStream so leave these
checks in to facilitate debugging in the future.

Replace wxLogWarning()s in wxOSX wxComboBox code with asserts.
This incidentally fixes compilation when not using PCH as wx/log.h was not
included but is also more correct as the messages meant for the programmer,
and not the user, should be given using asserts and not wxLog.
Also correct some asserts messages. In particular, don't mention the function
name in the message itself as it's already shown by the assert and using it in
the string itself isn't useful and simply introduces the risk of forgetting to
update it after refactoring, as happened here in r63105.

Allow to not create wxPaintDC in EVT_PAINT handler in wxMSW.
Failure to create a wxPaintDC in EVT_PAINT handler resulted in many serious

we detected that a handler didn't create a wxPaintDC but it seems better to
just handle this case gracefully for consistency with the other platforms.

wxPaintEvent and set to true when ::BeginPaint() is called from wxPaintDC
ctor and validate the update region of the window ourselves if it wasn't set

Correct test for parent being on screen in wxTLW::DoCentre().
The old test was needlessly complicated, didn't take all cases into account

Correct this by simply checking if the parent rectangle intersects the visible

Only disable use of non-ANSI functions in strict ANSI mode under Windows.
The changes of r62518 fixed compilation of wx headers in g++ strict ANSI mode
(enabled by th use of -ansi or -std=c++{98,0x} options) with mingw32 but
broke it when using g++ in ANSI mode under Unix. The problems arose at least
due to redeclaration of isascii() with different exception specifier and due
to the lack of wxCRT_StrdupA() definition in the library.
Fix this by simply not disabling the use of non-ANSI functions such as
isascii() and strdup() under Unix as they are still available in the headers
by default because of _GNU_SOURCE predefined by g++.
Notice that if _GNU_SOURCE is explicitly undefined, compilation would probably
still be broken. To fix this we might check whether __USE_SVID is defined
under Linux. Unfortunately doing tests in configure is not an answer as
wxWidgets might not be compiled with the same -std option as the programs
using it, so there is no obviously correct way to fix this.
