tFile tests fail under i686-pc-linux-gnu with -fno-inline

["John David Anglin" <dave at hiauly1 dot hia dot nrc dot ca>]

Under i686-pc-linux-gnu, the tFile tests fail due to incorrect output
when tFile.cc is compiled with `-O3 -fno-inline'.  The tests don't fail
when compiled with just `-O3'.  Here the diff for the output:

I don't know what's gone wrong.  With the same option, the tests don't
fail under hpux 10.20.  The full log output for the test is appended below.
