Make bits/math-finite.h conditions match other headers (bug 19205).
bits/math-finite.h declares -ffinite-math-only variants of various functions under conditions not matching those under which the normal versions are declared. * math.h only ever includes bits/mathcalls.h to declare float and long double functions if __USE_ISOC99, but bits/math-finite.h declares some float functions regardless (long double ones are conditioned on __MATH_DECLARE_LDOUBLE). (For C90 functions this isn't a conformance bug because C90 reserves the float and long double names, but is still contrary to good glibc practice. For some other functions in older XSI standards it *is* a conformance bug.) * Some functions are defined as inlines using lgamma_r functions under conditions where those lgamma_r functions are not themselves declared. * hypot is declared under __USE_XOPEN || __USE_ISOC99 in bits/mathcalls.h, __USE_ISOC99 only in bits/math-finite.h. * float and long double versions of Bessel functions should be limited to __USE_MISC (as in bug 18977). * gamma should not be declared for __USE_XOPEN2K (as in bug 18967). * remainder should be restricted to __USE_XOPEN_EXTENDED || __USE_ISOC99, not unconditional. * scalb should not be declared for __USE_XOPEN2K8, and scalbf and scalbl are non-POSIX (as in bug 18967). This patch fixes all these issues (it doesn't seem worth splitting them into separate patches or bugs). I put __USE_ISOC99 conditionals, where needed, around both float and long double declarations, even though formally redundant around the long double declarations because __MATH_DECLARE_LDOUBLE isn't defined without __USE_ISOC99; it seemed clearer that way. The missing declarations of lgamma_r functions are dealt with by directly using declarations of __lgamma*_r_finite, in the implementation namespace, rather than having the inlines rely on asm redirection of lgamma*_r. After this patch, there are some apparently redundant nested __USE_ISOC99 conditionals in lgamma / gamma definitions. These actually reflect a separate bug (the correct condition for the lgamma inline functions to set signgam is __USE_MISC || __USE_XOPEN, the condition under which signgam is declared, rather than disabling setting it if __USE_ISOC99, which includes XSI POSIX versions for which signgam *should* be set). They'll be fixed as part of a fix for that bug, which will also add tests for these inlines. I've put a note about more general conform/ test coverage for -ffinite-math-only on <https://sourceware.org/glibc/wiki/Development_Todo/Master#conformtest_improvements>, alongside other options for which this is also relevant (some of which have also had such bugs in the past relating to mismatched conditionals). I also intend to enable the main libm-test.inc tests for the math-finite.h functions, but some other bugs in __*_finite need fixing first.
