Travis Vitek commented on STDCXX-240:
-------------------------------------
Some of the compilers handle disabling of exceptions differently. With AIX, the
keywords remain valid, and are expected in some contexts.
The warnings shown above seem inconsistent as one message says the throw spec
is missing, and then the next says the exception spec is being ignored. A
simple testcase shows that this is the case. So I need to disable exception
usage in the library, but I need to leave the exception specs for at least one
platform.

> aCC has an option +noeh. When it is provided, __HPACC_NOEH will be
> defined. It would be nice for users to need to only use +noeh. For
> that,
> RWSTD_NO_EXCEPTIONS needs to be defined conditionally.

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