I thought about using colon but decided against it.  Tell me,
would:

	int:16;

be a bit field declaration or a field declaration with no
members?  Obviously the former, but the possibility of confusion
is not desirable.  It might make the language non-LALR as well.
Also, my use of [unsigned] was intended as part of the syntax, to
imply that unsigned could be used for the declaration.  Sorry for
the ambiguity.

Better would be into something like the Gnu C compiler.  Whatever
Stallman's political idiocies, the compiler does seem rather well
known.  The Small-C compiler has the drawback that it isn't a
complete implementation of C, that makes it kinda invisible to
those of us who have to do real work in C.  :-)

Would be nice.

Here is an extension to this idea: use short*n to indicate that
you want it packed if this is reasonable, and int*n to indicate
that you don't care if it is packed.
