Travis Vitek commented on STDCXX-240:
-------------------------------------
The original snippet provided above shows someone trying to build their code
without exception support, with a library was configured with exception
support. If I attempt to do this [e.g., build the library as normal, then build
the examples without exceptions], I get errors in the tests and examples where
we use exception keywords try/throw/catch. I'm guessing I should go through and
fix all of those issues and add those changes to the patch or I should open up
a new bug for the problem. Considering the issue is pre-existing and is fairly
large, it might be better to create a new bug for dealing with it.
I don't believe we should need to define the other macros explicitly. The
include order is such that we shouldn't have to. I do see that we define
_LIBC_THROWS to `throw ()' regardless of any of the other exception macros.
This is probably wrong.
I believe the error above was caused by building the library with -qnoeh, and
then attempting to build user code without it. Now that I think about it, that
is a bad idea anyways.

> 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.
