extra_tool_flags are:
-D__STDCPP_WANT_MATH_SPEC_FUNCS__
on a recent trunk. This is a typical newlib port. Not sure if this is a real
bug or not, but thought I’d forward it long.
This confused me at first, but I think what must be happening is that
your newlib port doesn't use c_model=c_global, so it uses a <cmath>
header that doesn't #include <bits/spec_fun.h>.
What does your $target/libstdc++-v3/config.log show instead of
c_global here?
configure:16391: "C" header strategy set to c_global
(Alternatively, just look at where the
$target/libstdc++-v3/include/cmath symlink points).
