Pure 32-bit and 64-bit win32 assembly windows programs and some gcc compiler to assembly custom win32 header stuff
To assemble the programs you need the NASM assembler. All headers are generated via macro's so you can compile on every platform and don't need specific Windows linkers. You could run the build.sh script to assemble all the programs.
In the folder custom-gcc is a little project which uses the gcc compiler to compile c code to assembley which then is assembled with custom headers via nasm. This gives you in essence the best of both worlds, but it is still experimental.
