ibstdc++: Shut up -Wattribute-alias warning [PR109694]
I've followed what other files do, using attribute alias with not really
matching function type (after all, it isn't really possible when it is a
constructor), but seems I've missed it warns:
../../../../../libstdc++-v3/src/c++98/ios_init.cc:203:8: warning: ‘void std::ios_base_library_init()’ alias between functions of incompatible types ‘void()’ and ‘void
+(std::ios_base::Init::)()’ [-Wattribute-alias=]
203 | void ios_base_library_init (void)
| ^~~~~~~~~~~~~~~~~~~~~
../../../../../libstdc++-v3/src/c++98/ios_init.cc:78:3: note: aliased declaration here
78 | ios_base::Init::Init()
| ^~~~~~~~
The PR talks about clang++ warning there (which I think isn't really
supported, libstdc++ sources ought to be built by GCC), but it warns
when built with GCC too.
The following patch fixes it by doing what other libstdc++ sources do in
those cases.
