Obtaining builtin function list.

[Brendon Costa]

How can I get a full list of all GCC C++ built-in functions that may be
used on a given platform or GCC build?

For example, __cxa_begin_catch(), __cxa_end_catch(), __builtin_memset ...

I am currently working with GCC 4.0.1 source base.

Thanks,
Brendon.
