--- Comment #17 from joseph at codesourcery dot com <joseph at codesourcery dot com> --- And, when long is 64-bit, there is no corresponding standard function to round to 32-bit integer with "invalid" raised for out-of-range results - but there is (undocumented) __builtin_irint. So if you document __builtin_irint, machine-specific built-in functions should only be needed here if the functionality is desired in the presence of math-errno (cf. the proposals to change the default there) - and even there, machine-independent no-errno built-in functions might be better.
