- 22 issue18640 : generalization of posix build in distutils/sysconfig.py

Hints:
a) at configure time define environment variable CPPFLAGS with minimum supported version like this   "-DWINVER=0x501 -D_WIN32_WINNT=0x501  -DMS_COREDLL=1", i.e XP is now minimum. MS_COREDLL is required for ctype module
b) at configure time define environment variable CCSHARED with minimum supported version like this: "-DWINVER=0x501 -D_WIN32_WINNT=0x501". Remark use same values as CPPFLAGS
c) use --without-libm
d) use --enable-shared
e) use --with-system-ffi
