Travis Vitek updated STDCXX-204:
--------------------------------
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.

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.
