OK, how about this?  It doesn't look like config.in had been regenerated 
in a while, so some of the changes appear to be unrelated to the change 
to configure.ac.  Thank you for your help, by the way.


2004-05-31  Aaron W. LaFramboise <aaronraolete36@aaronwl.com>

   * system.h: Prototype getpagesize if missing.
   * configure.ac: Add getpagesize to gcc_AC_CHECK_DECLS.
   * configure: Regenerate.
   * config.in: Regenerate.
