Author: marcel Date: Sun Jun 20 00:34:06 2010 New Revision: 209358 URL: http://svn.freebsd.org/changeset/base/209358 Log: Unbreak platforms with char unsigned by default. Oddly enough, GCC isn't satisfied with a simple cast to int in the check against EOF, so the fix is a bit involved by actually having to go through a temporary variable.
