For the record, you can simulate clang's modules using any compiler
by simply compiling in everything as a single translation unit. A
simple shell script can create a file which includes all the source
files at once.

If it works as a single translation unit, it'll work under clang
modules. If it doesn't, well then you've got some ODR violation going
on (very common in source files which assume they own their
translation unit) and it may or may not work under clang modules

I have taken care that API Bind works correctly in single translation
unit use cases. I'll admit the gotchas surprised me at the time.
