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.
See #11374.

There are 2 unrelated problems with these functions under Mac:

a) Metrowerks MSL CRT implements them strictly in C99 sense and

|
doesn't support (very common) extension of allowing to call
|
|
mbstowcs(NULL, ...) which makes it pretty useless as you can't
|
|
know the size of the needed buffer
|
|
b) OS X <= 10.2 declares and even defined these functions but

doesn't really implement them -- they always return an error
|
|
|
|
So use our own replacements in both cases.
