Out-of-line mode should support floating point types of arbitrary size and signness

Created originally on Bitbucket by maxbelanger (Max Bélanger)

Related to issues 69 and 73, and similar to the change made in 43ee9d0dd03f to introduce the following syntax:

typedef int... foo_t;

It would also be useful to support floating-point types in such a way. We are working on writing an abstraction layer over CoreFoundation-based DLLs on Mac OS X, which defines CGFloat, for example, as being a float in i386 but as a double in x86_64 (IIRC).

Is this something planned or in the works for a future version? How can I help?
