>Description:
When bootstrapping mainline on mips-sgi-irix6.5 with
SGI's native compiler, I get the following error:

gmake: *** [bootstrap-lean] Error 2
===========================================================

If I add explicit casts to "void*" for the three arguments,
the bootstrap is performed without errors.
I'm not sure, however, if that's a correct fix.

Maybe it's not even gcc's fault, but a bug in SGI's
compiler. But even then: if it prevents bootstrapping,
there should be a workaround.
