It is not impossible.

I use mingw.org's MinGW, where the header which defines _WIN32_WINNT
is included by every header file.  So as soon as you #include
anything, _WIN32_WINNT is already defined.

Maybe it isn't so in the headers you are using, but that doesn't mean
it is so for everyone.

And I don't see how is that relevant: even if _WIN32_WINNT is
undefined before that place, my suggestion is to change this:

 # else
 #  define _WIN32_WINNT 0x0501

into something that defines _WIN32_WINNT to 0x0600 under the condition
that the gthread patch is being used, and to 0x0501 otherwise.  This
should solve everyone's problem, right?

See above: that is not necessarily what happens, not in all the cases
anyway.
