Instructions for building native gnumake.exe for Windows

From cygwin or other unix shell in this directory:

1) get archive:      wget http://ftp.gnu.org/gnu/make/make-4.4.1.tar.gz
2) unpack archive:   tar xf make-4.4.1.tar.gz
3) go to sources:    cd make-4.4.1
4) patch make:

 - fix bugs under Windows:
  (detect too small or empty source Makefile)
  patch -Np1 -i ../make-4.4.1-sub_proc.patch
  (don't hang on Ctrl-C)
  patch -Np1 -i ../make-4.4.1-win32-ctrl-c.patch

 - optionally, fix inconsistency with fake function arguments, see http://savannah.gnu.org/bugs/?49841
  patch -Np1 -i ../make-4.4.1-SV49841.patch
 
 - optionally, add ability to enable/disable warnings about use of undefined numeric variables (function arguments)
  patch -Np1 -i ../make-4.4.1-warn-noargs.patch

 - optional optimization patches
  patch -Np1 -i ../make-4.4.1-expand.patch
  patch -Np1 -i ../make-4.4.1-sort.patch
  patch -Np1 -i ../make-4.4.1-filter.patch

 - support for ANSI color escape sequences in Windows console
  patch -Np1 -i ../make-4.4.1-win32-colors.patch

 *** development patches for makefile writers ***

 - show warnings about use of environment variables in makefiles
  patch -Np1 -i ../make-4.4.1-warn-env.patch

 - disable builtin rules/variables, show warnings about use of
   undefined variables in makefiles, except function arguments
   (always run with -rR --warn-undefined-variables)
  patch -Np1 -i ../make-4.4.1-no-builtin-warn-undef.patch

5) if needed, enable case insensitive file names support:
  sed -i 's/.* HAVE_CASE_INSENSITIVE_FS .*/#define HAVE_CASE_INSENSITIVE_FS 1/' ./src/config.h.W32

6) fix build flags:
  - to build for windows7, add compiler define /D_WIN32_WINNT=0x601
   sed -i 's@ NDEBUG"@ NDEBUG /D_WIN32_WINNT=0x601"@' ./build_w32.bat

7) run dos prompt:   cmd.exe /c "start cmd.exe"
8) setup compiler:
  - to build for windows7/x64:
   "c:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat" x86_amd64

  - to build for windows7/x86:
   "c:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat" x86

9) do compile:       build_w32.bat --verbose --without-guile
10) build result:    WinRel\gnumake.exe --version
