             Bug #: 52166
           Summary: c++0x required to import standard c++ headers?
    Classification: Unclassified
           Product: gcc
           Version: 4.6.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: scovich@gmail.com


Several of the standard C++ wrapper versions of C headers can only be imported
with c++0x support enabled (tested on both cygwin and x86_64-linux):

#error This file requires compiler and library support for the upcoming ISO C++
standard, C++0x. This support is currently experimental, and must be enabled
with the -std=c++0x or -std=gnu++0x compiler options.

Workaround is to #include <foo.h> instead of <cfoo>, but it's annoying given
that the former is supposedly The Right Way for C++ programs to bring in the
header.

Affected files:

ccomplex
cfenv
cinttypes
cstdint

It's the right way for C++11 programs to bring in the headers - the headers
don't exist in C++03

N.B. if we enabled <cstdint> in C++03 mode users would (rightly) complain that
it makes it harder to write portable programs, and it would be a problem for
autoconf-style tests which check for the existence of <cstdint> to determine
whether a C++11 compiler is being used.
