I dug out a copy of VS Express, and traced into the header files. It
does seem to be specific to MSDN. It actually lets you use "strdup"
but then gives you a warning that the POSIX name is deprecated (in
favor of the ISO C++ name).

_Check_return_ _CRT_NONSTDC_DEPRECATE(_strdup) _CRTIMP char * __cdecl
strdup(_In_opt_z_ const char * _Src);

#define _CRT_NONSTDC_DEPRECATE(_NewName) _CRT_DEPRECATE_TEXT("The
POSIX name for this item is deprecated. Instead, use the ISO C++
conformant name: " #_NewName ". See online help for details.")

#define _CRT_DEPRECATE_TEXT(_Text) __declspec(deprecated(_Text))

So essentially, it just adds __declspec(deprecated(...)) unless you
set the macro yourself. Which means it just toggles the warning, and
I'm guessing MinGW doesn't have the compatibility layer into the CRT
that MSVC has.
