             Bug #: 54451
           Summary: c++11/random.cc build failure when
                    _GLIBCXX_USE_C99_STDINT_TR1 is not defined in config.h
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libstdc++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: andris.pavenis@iki.fi


When _GLIBCXX_USE_C99_STDINT_TR1 defined in config.h neither of bits/random.h
and bits/random.tcc gets included and as result c++11/random.cc does not
compile:

random.cc:72:3: error: 'random_device' has not been declared

Noticed that when trying to build recent SVN version as Linux to DJGPP
cross-compiler. Tested versions 2012-08-30 and later.

Commenting out '#ifdef _GLIBCXX_USE_C99_STDINT_TR1' fixed build problem, but
I'm not sure that it is correct solution.
