h2incn tries to directly convert C/C++ headers to
Nasm-style include files, and can be used in a
makefile. It is useful if you want to use the same
structures or external variable declarations in C
and assembler code, and you don't want to use two
separate files and update both each time you
change something. It is written in a mix of C and
C++ code. It currently works for simple files.
