ok... I figured out what it was (it was me being too smart for my own good).
A long convoluted story, but even though /usr/ccs and gcc were locally 
available, the gnu 'as' was not available for small periods of time, 
and it looks like gcc runs back to /usr/ccs/bin/as by default.


Although, one could argue that - if you compile with --with-gnu-as=...
you should get a *fatal error* if that gnu as is not available, not
an attempt to use sun's version...
