[PATCH] For PR libstdc++/33203.

[Danny Smith]

Hello, 

The attached fixes libstdc++/33203 by factoring out the
definition of os error constants into an os-specific config file,
error_constants.h, that is installed in <host>/bits/error_constants.h.

I have left all the ifdef _GLIBCXX_HAVE_E*'s in the generic error_code.h
and in the configury. I think they should be removed eventually, in
favor of os-specific error_constants.h.

Is this approach OK.

I have not yet attempted to hack types_std_c++0x.cc testsuite to pass on
mingw32 :( 

:ADDPATCH libstdc++:
