The following construct seems to work around the problem for GCC 3.2, though
it's potentially very dependent on compiler version, optimization and whatnot:

int foo(...) { ... }
int bar(...) { __builtin_return(__builtin_apply(foo,...)); }

becomes

int foo(...) { ... }
int bar1(...) { __builtin_return(__builtin_apply(foo,...)); }
void bar2(...) {
    __builtin_apply(bar_tmp,...);
    asm("ld [%sp-128],%i0");  /* %i0 is the SPARC return register */
}
int (*bar)(...) = (void *)bar2;
