thanks!

On Darwin, the test case now builds (checked on a 32b host [powerpc] with a=
 64b
multilib) and a 64b (x86_64) host.  The 32b multilib xfails the execute (as
expected w/out int128 support)

On both powerpc (64b multilib) and x86_64:

test01 fails with :=20
src-local/gcc-master/libstdc++-v3/testsuite/20_util/to_chars/long_double.cc=
:136:
void test01(): Assertion '!strcmp(to_chars_buffer, printf_buffer+strlen("0x=
"))'
failed.

(not analysed why yet).=
