- * Declaration for old-style function pointer type. This is now used only
- * in fmgr_oldstyle() and is no longer exported.
- *
- * The m68k SVR4 ABI defines that pointers are returned in %a0 instead of
- * %d0. So if a function pointer is declared to return a pointer, the
- * compiler may look only into %a0, but if the called function was declared
- * to return an integer type, it puts its value only into %d0. So the
- * caller doesn't pick up the correct return value. The solution is to
- * declare the function pointer to return int, so the compiler picks up the
- * return value from %d0. (Functions returning pointers put their value
- * *additionally* into %d0 for compatibility.) The price is that there are
- * some warnings about int->pointer conversions ... which we can suppress
- * with suitably ugly casts in fmgr_oldstyle().
