Travis Vitek updated STDCXX-240:
--------------------------------

    Attachment: stdcxx-240.patch

Well, the test suite doesn't build cleanly if _RWSTD_NO_EXCEPTIONS is defined. There are many undefined variable warnings, and many places that use keywords try/throw/catch without checking the macro first.


I can't fully say that this is working completely because many of the tests don't compile when _RWSTD_NO_EXCEPTIONS is defined. I also get some warnings because of mismatches. On AIX, for example, I get these warnings.

"/amd/devco/vitek/stdcxx/trunk/include/new", line 216.7: 1540-0419 (W) An exception-specification must be specified as "throw(std::bad_alloc)" to match the implicit declaration.
"/amd/devco/vitek/stdcxx/trunk/include/new", line 216.7: 1540-1088 (W) The exception specification is being ignored.
"/amd/devco/vitek/stdcxx/trunk/include/new", line 223.6: 1540-0419 (W) An exception-specification must be specified as "throw()" to match the implicit declaration.

Not sure how to proceed with this. I'm attaching the patch that checks the above mentioned macros in the appropriate config headers. It does nothing else.

> We should do this AND test it -- not just on aCC but in general with all compilers that support this feature.
