On alpha, sqrt (a C90 function) brings in references to fegetenv
(C99), resulting in linknamespace test failures:
[initial] __sqrt -> [libm.a(w_sqrt.o)] __ieee754_sqrt ->
[libm.a(e_sqrt.o)] __feholdexcept -> [libm.a(feholdexcpt.o)] fegetenv
This patch fixes this by making __feholdexcept call __fegetenv instead
of fegetenv.
Tested for Alpha (compilation only).
[BZ #20768]
* sysdeps/alpha/fpu/feholdexcpt.c (__feholdexcept): Call
__fegetenv instead of fegetenv.
Continuing the fixes for C90 libm functions calling C99 fe* functions,
this patch fixes the case of feholdexcept by making it a weak alias of
__feholdexcept and making the affected code call __feholdexcept.
Tested for x86_64 (testsuite, and that disassembly of installed shared
libraries is unchanged by the patch). Also tested for ARM
(soft-float) that feholdexcept failures disappear from the
linknamespace test failures (fesetenv, fsetround and feupdateenv
remain to be addressed to complete fixing bug 17748).
[BZ #17748]
* include/fenv.h (__feholdexcept): Declare. Use
libm_hidden_proto.

define as weak alias of __feholdexcept. Use libm_hidden_weak.
