The original thread was "libio testsuite: timeout compiling tFile.cc".  Bundled
with the patches to work around the timeout was a patch to fix the compile
problem for tfformat.

This problem was created by the following patch:

2000-05-23  Zack Weinberg  <zack@wolery.cumb.org>

        * tfformat.c: Include stdlib.h.

Here is a sample of the conflicts:

I don't believe that the conflicts can be eliminated because the header
iostdio.h is supposed to define "a stdio-like environment".
