I just added new defines for some float math functions that were missing from the list and slightly reorganized the list into something slightly closer to alphabetical order. The for HP-UX doesn't do this sort of thing: extern double acos(double __x) __ATTR_CONST__; #define acosf acos /**< The alias for acos(). */ Technically, avr doesn't have a proper acosf. If float and double differ, acos won't handle exceptional values correctly for acosf. So, I think the AC_DEFINEs for the float variants should be removed or conditioned on some libc version. In my package, configure checks were added so that we now check all the C99 float variants. As a result, we now use the libc version instead of the stub version for some functions.

Originally, I wrote a patch to add declarations for missing C99 functions on hpux to math.h. They were declared when __cplusplus was defined. But then I realized they would be better in cmath as then all targets could potentially benefit. They could be guarded by something like _GLIBCXX_NEED_C99_DECLARATIONS. It could go in os_defines.h. On hpux11, the configure checks are sufficient. I think they are also sufficient on linux (test in progress).

I defined _GLIBCXX_USE_C99_MATH_FUNCS and _GLIBCXX_USE_BUILTIN_FMAF in config/os/hpux/os_defines.h: +// Import C99 functions in in in namespace std in C++11. +// Missing functions are handled by stubs.

Currently, _GLIBCXX_USE_C99_MATH_FUNCS and _GLIBCXX_USE_C99_MATH_TR1 are only enabled when configure detects the full set of C99 functions.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=114101 --- Comment #1 from John David Anglin --- Created attachment 57529 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=57529=edit Preliminary patch. Still need to review float and long double stubs to make sure they are complete for libgm2. Tested so far on hppa64-hp-hpux. configure, config.h.in and src/c++98/Makefile.in need regeneration with autoconf, autoheader and automake, respectively.
