I'll try this when I get back home. I think gcc should return struct
values in registers anyway (ignoring -fpcc-struct-return) if the caller
and callee can follow the same struct-return convention (i.e. inline and
static functions). Is there a fallacy in my thinking? I hope somebody more
experience can tell me if this is easy to 'fix' in egcs. 

Thanks a bunch. -Hasdi
