Continuing the fixes for C90 libm functions calling C99 fe* functions, this patch fixes the case of fesetenv by making it a weak alias of __fesetenv and making the affected code (including various copies of feupdateenv which also gets called from C90 functions) call __fesetenv. Tested for x86_64 (testsuite, and that disassembly of installed shared libraries is unchanged by the patch). Also tested for ARM (soft-float) that fesetenv failures disappear from the linknamespace test results (fsetround and feupdateenv remain to be addressed to complete fixing bug 17748). [BZ #17748] * include/fenv.h (__fesetenv): Use libm_hidden_proto. * math/fesetenv.c (__fesetenv): Use libm_hidden_def. * sysdeps/aarch64/fpu/fesetenv.c (fesetenv): Rename to __fesetenv and define as weak alias of __fesetenv. Use libm_hidden_weak. * sysdeps/alpha/fpu/fesetenv.c (__fesetenv): Use libm_hidden_def. * sysdeps/arm/fesetenv.c (fesetenv): Rename to __fesetenv and define as weak alias of __fesetenv.
