libstdc++: Fix -Wnarrowing in <complex> [PR116991]
When _GLIBCXX_USE_C99_COMPLEX_ARC is undefined we use the generic
__complex_acos function template for _Float32 etc. and that gives a
-Wnarrowing warning:
complex:2043: warning: ISO C++ does not allow converting to '_Float32' from 'long double' with greater conversion rank [-Wnarrowing]
Use a cast to do the conversion so that it doesn't warn.
libstdc++-v3/ChangeLog:
PR libstdc++/116991
* include/std/complex (__complex_acos): Cast literal to
destination type.
