Subject: [Bug c/46155] Bug with generation of float.h header file on AIX

--- Comment #13 from Kalle Olavi Niemitalo <kon at iki dot fi> 2010-11-18 08:10:20 UTC ---
Earlier, I thought GCC would eventually have to add some libc-specific
definitions to <float.h> anyway, in order to make FLT_ROUNDS call a function in
the C library and map the results correctly, and the IBM fprnd_t and function
declarations could then be added at the same time; but according to bug 30569,
FLT_ROUNDS is supposed to call a built-in function instead.

FLT_EVAL_METHOD has a similar "???" comment above it, but C99 says it shall be
a "constant expression[s] suitable for use in #if preprocessing directives", so
cannot expand to a function call.
