Well, I was also thinking "does anything else out stdarg.h vary per-platform".  
(I dunno.  va_copy and va_end look fairly straightforward, but is rounding up 
to 4 is good for va_start for everybody?)

Cool.

Cool!  Yes please.  Before that, I suspect that fabrice had it under control.  
The first release of qemu was in may 2003:

  http://lists.gnu.org/archive/html/tinycc-devel/2003-03/msg00084.html

Before that (and for a while after), Fabrice had plenty of time for tcc, so 
I'd expect any dropped patches before then to be for a reason.  It's the last 
couple years (since qemu made it big) that's the trouble...
