After above patches user must regenerate configure script.

Hints:
a) at configure time define CPPFLAGS with minimum supported version like this   "-DWINVER=0x501 -D_WIN32_WINNT=0x501", i.e XP is now minimum
b) use --without-libm 
c) do not use yet --enable-shared

Notes:
a) previous mingw patch (issue3871 posted in 2008) contain code that define w2k as minimum . Now python evolve and minimum is xp. 
b) previous patch nos not define libm in configure script . Instead to updated configure use tis flag
c) will be included in additional patch-set related to build of standard extensions.
