Goal is statically linked python executable (python.exe).

- 01 Issue17148 : nt thread model detection
- 02 issue17590 : translate gcc internal defines to python platform specific defines
- 03 issue17591 : use header in lowercase
- 04 issue17592 : configure MACHDEP and platform for build
- 05 issue17594 : preset configure defaults
- 06 issue17595 : configure largefile support for windows builds
- 07 issue17596 : add wincrypt.h in Python/random.c
- 08 issue17597 : add $srcdir/PC to CPPFLAGS
- 09 issue17598 : init system calls

- 14 issue17603 : AC_LIBOBJ replacement of fileblocks
- 15 issue17604 : use main() to start execution

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.

There are patches on #10615 which may be of some use here.

please follow build of core modules - issue18653 .

There are a pile of mingw enhancement requests with this and
#18653, #18654 and #19245 being meta issues.  What is the official status of mingw within Python?  Is the originator of these issues solely responsible for taking them forward?
