Yes, stoll and stoull tests are UNSUPPORTED.

We also have:
UNSUPPORTED: 21_strings/basic_string/numeric_conversions/char/stold.cc

The rest of the non wide character conversion tests pass.

The stoll and stoull tests pass when dg-require-string-conversions is 1.=C2=
=A0 The
stold test
fails, I think because it returns LDBL_MAX instead of HUGE_VALL (inf).=C2=
=A0 See
_GLIBCXX_HAVE_BROKEN_STRTOLD comment in /config/os/hpux/os_defines.h.

There is a problem with std::stof.=C2=A0 It throws an out of range exceptio=
n for 0.=C2=A0
It needs to
check for 0 value.=
