Thanks Nicholas The fact that the C code resulting from the translation is not humanly readable is not important to me. I only intend to compile the C code and link it against other libraries.
/* */ style comments not being supported is a minor problem. Infix not being supported is a slightly bigger deal, but manageable. Thanks! I'll keep on experimenting.
