The original work - I have no idea. I do know that some things were
quite different to what newlibc exports which has caused some confusion.

I'm working of the documentation at www.opengroup.org (searching on
google is the easiest way to a good entry point). They don't mention
draft versions there.. I'm goping to have to dig up the current IEEE
specs I can see.

You've done an excellent bit of research for me. It's my turn to plead
business - I'm hoping to get quite a bit done this weekend though, so
I'll actually read and cross reference what you've put together.

If the project uses autoconf, that would be better tested as
#if HAVE_FEATURE

or even just have
#ifndef HAVE_FEATURE
#define func ;
#define func ;
#define func ;
#endif
in one of your core makefiles.
'course if it's not autoconf'd, what you've got is absolutely correct.
