Subject: [PATCH] Fix build with TDM-GCC

@newfrenchy83 said that the build is failing:
https://github.com/wesnoth/wesnoth/commit/37225d24eaa52183f897e223dc3847bf89c89282#commitcomment-25629052

It looks like TDM-GCC uses Windows XP development headers, unfortunately.
However, the problem is easy to work around by simply #defining the missing
value ourselves. We should consider dropping TDM-GCC support after the 1.14
release, though.
