Hi,
This could be an SVN branch for now (*). I will get on to it. I should
be possible to use the same template for building the 32 bit msvcr90
import library for MinGW to build on for 64 bit mscvr90. If not then
the best long term solution here would be to have an masm version of
scale_mmx64.c. The smoothscale code has been around for awhile and
without any bug reports filed. So the code should be stable.

(*) For other maintainers, this would also be a test case for getting
SVN merges working properly by adding the proper tags to trunk.

Hello,
the attached patch and source files contain a workaround for building
pygame with MMX scaling support for 64-bit Windows using Visual
Studio and mingw-64-bit.
When compiling scale_mmx.c without -D_NO_MMX_FOR_X86_64 using the
64-bit Visual Studio compiler the file scale_mmx64_msvc.c is
included, which has all asm code replaced by function calls. The asm
containing functions are implemented in scale_mmx64_gcc.c, which can
be compiled independently with mingw-64-bit:
x86_64-w64-mingw32-gcc.exe -c src/scale_mmx64_gcc.c
-fno-leading-underscore -o obj/win64/scale_mmx64_gcc.obj
The resulting scale_mmx64_gcc.obj is then linked during the MSVC
build process.
The patch should not interfere with other compilers (not verified).
It is just a workaround until mingw-64-bit has support for using the
msvc9 runtime. It is probably not a good idea to apply the patch to
the main trunk since it duplicates code.
The resulting 1.9.2pre binaries pass all tests, except
freetype_font_test.
The patch also tries to import vidcap from the VideoCapture package.
