Please re-read the discussion if you missed the purpose of the
patch.
apsi.f: In subroutine `uvset':
apsi.f:4327: internal compiler error: RTL flag check: REG_POINTER used with unexpected rtx code `mem' in copy_rtx_and_substitute, at integrate.c:2065
Jan's patch ensures that REG_POINTER() only is called with a REG
rtx. If the rtx is not a REG, the rest of the conditional does not make
sense, so it seems like a reasonable fix.
