Sorry, this is incorrect.  The Sparc `struct' return convention did
change from GCC 2.1 to GCC 2.2.1, but it's not compatible with Sun's
compiler by default in 2.2.1.

Apparently the change in return conventions was a mistake,
and it'll be reversed in future GCC versions.

Thus, if your code returns small structures or unions,
don't try to link 2.1-generated code with 2.2- or 2.2.1-generated code;
and probably ditto for GCC releases after 2.2.1.
