Problem introduced after 1.0rc2 on AIX with xlc

I looked at the UFUNC_CHECK_STATUS implementation for AIX and put in
some print statements.  The the fpstatus returned to fp_read_flag is
always indicating an FP_INVALID so
UFUNC_CHECK_STATUS return 8.

But the code looks fine to me.  It seems a little odd that it would
always indicate this flag.  Where else can I look to try to see what
it goiing on?  Do you think this is worth worrying about, or should we
just have use seterr(all='ignore')?  I am willing to try to hunt this
down, but I don't know much about the internals of numpy.

Thanks
