Extended Description

We need this for tgmath.h, Doug volunteered to tackle this.

[lattner]

Oh, when this is done, we should remove __builtin_overload.

[lattner]

Doug, is this work complete?

[DougGregor]

Not until we have proper name mangling for "overloadable" functions in C. It might work with always_inline now.

[DougGregor]

This is now implemented in Clang. Documentation is here:
