3.[01] bootstrap failure on alphaev6-unknown-linux-gnu in compex_io.cc

[Brad Lucier <lucier at math dot purdue dot edu>]

On alphaev6-unkown-linux-gnu, with 3.[01] and today's CVS, I get
a good bootstrap comparison, but the bootstrap fails in 3.1 with

FWIW, I had a good bootstrap today on sparc-sun-solaris2.8 with both trunk
and mainline.  (Make check is still running.)
