On most machines, the struct convention is used unless we are
using gcc and the type is of a special size. */
/* As of about 31 Mar 93, GCC was changed to be compatible with the
native compiler. GCC 2.3.3 was the last release that did it the
old way. Since gcc2_compiled was not changed, we have no
way to correctly win in all cases, so we just do the right thing
for gcc1 and for gcc2 after this change. Thus it loses for gcc
2.0-2.3.3. This is somewhat unfortunate, but changing gcc2_compiled
would cause more chaos than dealing with some struct returns being
handled wrong. */
