Travis Vitek updated STDCXX-677:
--------------------------------
Attachment: 8.cstdint.stdcxx-677.cpp
stdcxx-677.patch
In that case, then I don't think that this really needs to be fixed. When the
contents of the `tr1' directory are moved to `include', our stdint.h would get
picked up by the preprocessor before /usr/include/stdint.h. That would
eliminate the problem entirely, unless the user explicitly included
/usr/include/stdint.h
In case you don't agree, I'm providing a patch, test, and description. I wasted
the time writing it, so I might as well show something for my efforts.

STDCXX-677
* include/tr1/cstdint: undefine macros that may have been defined by
system provided stdint.h to prevent name collisions
* etc/config/src/headers.inc: add stdint to the list of headers to test for
at configuration time
* tests/regress/8.cstdint.stdcxx-677.cpp: regression test to verify no
name collision when tr1/cstdint included after stdint.h

> The following testcase fails to compile because both the C library stdint.h

> like we need to avoid defining the macros if a previous definition already
