Yes but without --with-mpc=, configure will only find it if it's installed 
in a default search path.  Not everyone does this (especially since it 
requires root).  I try to be explicit in describing my test conditions in 
patch postings so these issues aren't left ambiguous.

Okay great, thanks.

By the way, I'm curious why sh-* needs -mieee for builtin-math-7.c and not 
other tests using Inf like builtin-isinf_sign-1.c.  Is it Inf or Nan that is 
the issue?
