As filed by Jonathan in the PR, I've screwed up the requires syntax
in the extended floating point specialization:
- requires(__complex_type<_Tp>::type)
+ requires requires { typename __complex_type<_Tp>::type; }
and doing this change resulted in lots of errors because __complex_whatever
overfloads from extended floating point types were declared after the
templates which used them.
The following patch fixes that.
Bootstrapped/regtested on x86_64-linux and i686-linux, additionally
I've tested that with _GLIBCXX_HAVE_FLOAT128_MATH not being defined
while __STDCPP_FLOAT128_T__ defined one can still use
std::complex<std::float128_t> for basic arithmetic etc., just one can't
expect std::sin etc. to work in that case (because we don't have any
implementation).
