* mingw-w64-make/PKGBUILD:
- prepare: build with batch file build_w32.bat (instead of autotools,
- since autotools approach is not fully supported for Windows builds).
- overwrite default executable name 'gnumake' with 'mingw32-make'.
- cd to src dir of package to apply package patches, since the dir
structure was changed with make version 4.3.
- check: move check section in package to separate function check.
- use overall helper function defining the executable dir.
* mingw-w64-make/make-check-load-feature.mak:
- add CFLAGS the user can pass to the makefile on the command line
- simplify setting of default value of LIBS
* mingw-w64-make/make-4.3_undef-HAVE_STRUCT_DIRENT_D_TYPE.patch:
- add this patch which #undefs HAVE_STRUCT_DIRENT_D_TYPE for any compiler.
NOTE: The guard for MINGW64 does not suffice, it is required for MINGW32, too.
