Re: ISO C violation (really -- style & string pasting)

I agree in general, and I will definitely do the fix in a way
that won't break anyone else, but in my case, since I own the
whole tool chain, I can fix it.  (And, in fact, already have,
based on now-obsolete source bases.)

I suspect (but certainly don't know) that in the Sparc case
it doesn't trip over the prefix "_" problem, and thus isn't 
a namespace pollution issue.  A single leading _ is perfectly
reasonable if you don't prefix them to user symbols.
