Yes it looks very nice so far.

Right.	Someone else added that stub.asm in the libc source is all that
it is used for.

Right.	NASM looks like the way to go for stand-alone pmode assembly stuff.

True, but even ANSI leaves some other issues which can vary from one
compiler to the next.  DOS compilers have lots of differences.	Maybe
Unixy ones don't, hence the absence of an implementation details document.
