clang and __float128 bug/error

Question

I\'ve successfully compiled the current 3.3 branch of clang. But then C++ compilation of any file fails with the bug/error. Can that be fixed?

I don't think clang supports __float128. It may be the same type as long double (which is 16 bytes in clang) so it may be a simple case of inserting:

#define __float128 long double

or:

typedef long double __float128;

somewhere early in your include chain.

I'm not guaranteeing that will work but it may, and it's probably best to try it out rather than wait until clang starts supporting more gcc extensions.

Either that, or switch to gcc, if that's an option. I'm pretty certain that gcc supports all of the gcc extensions :-)
