Subject: Re: [SG10] Adding a macro to identify the ABI

I think it makes sense to have semi-standard macros for this, and while
these aren't standard features I think SD-6 could be an OK home for them.
Do you anticipate needing any way to detect abi variants (eg, ARM ABI is
itanium with tweaks)?
I think some kind of version could be useful for both macros, but that
could be added later.

I was wondering if it would be possible to add a macro to identify the
underlying ABI that the C++ runtime is using? Although itanium is the more
popular choice, there are alternative ABIs such as the one which Microsoft
uses. I would propose something like the following:
They would be defined to 1 based on which is being used. This would allow
the implementation to change the behavior based on the ABI being used.
