[Bug libstdc++/20071] New: [4.0 regression] newlib target testsuite regressions: libstdc++: tr1/6_containers/tuple

["hp at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Between LAST_UPDATED: "Fri Feb 18 00:18:46 UTC 2005" and
"Fri Feb 18 15:14:59 UTC 2005" these regressions were
introduced on trunk for cris-axis-elf:

excess errors)

with the message in libstdc++.log being all similar for all the regressing
tests:

/home/hp/cvs_areas/combined/cris-regobj/cris-unknown-elf/libstdc++-v3/include/tr1/functional:139:
error: 'wstring' is not a membe\
r of 'std'^M
/home/hp/cvs_areas/combined/cris-regobj/cris-unknown-elf/libstdc++-v3/include/tr1/functional:139:
error: 'wstring' is not a membe\
r of 'std'^M
/home/hp/cvs_areas/combined/cris-regobj/cris-unknown-elf/libstdc++-v3/include/tr1/functional:139:

nvalid^M
/home/hp/cvs_areas/combined/cris-regobj/cris-unknown-elf/libstdc++-v3/include/tr1/functional:139:
error: explicit specialization \
of non-template '<type error>'^M

The author of the only matching change is CC:ed.

It seems like the use of std::wstring in include/tr1/functional
isn't properly #ifdef:ed or something.
Elsewhere in libstdc++ I see use of #ifdef _GLIBCXX_USE_WCHAR_T
wrapped around wstring grep matches.
(This seems like an obvious fix.)  The cris-axis-elf is a newlib target.
I see the same failures on mmix-knuth-mmixware, another newlib target.
