            Bug ID: 60326
           Summary: Incorrect type from std::make_unsigned<wchar_t>
           Product: gcc
           Version: 4.8.1
            Status: UNCONFIRMED
          Severity: normal

         Component: libstdc++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: kristian.spangsege at gmail dot com

The `std::make_signed` and `std::make_unsigned` templates appear to be
incorrectly implemented in GCC 4.8.1.

In particular, both `std::make_signed<wchar_t>::type` and
`std::make_unsigned<wchar_t>::type` produces the type `wchar_t`.

I don't claim to know what the right behaviour is, but it seems wrong, what is
currently done.

Clang 3.4 with `libc++` does this on x86_64:

std::make_unsigned<wchar_t>::type --> int
std::make_unsigned<wchar_t>::type --> unsigned

which seems more reasonable.

The most relevant section in the C++11 standard appears to be 20.9.7.3
[meta.trans.sign].

It looks that this failure was fixed between r208406 [1] and r208419 [2].

The ICE has been fixed between r205679 (2013-12-04, ICE) and r206069
(2013-12-17, OK). It is likely r205785 for trunk and r207390 for 4.8.

> That's good news, thanks.  Did you do a testsuite run for all languages?

Sorry, didn't have time for that -- the repeated 4.9 builds and tests caused
other build-and-test jobs to pile up and I need to get those done first.
