Hi Tom,

The nightly tests buildok and pass-5 tests failed due to the following 
checkin:

2006-03-15 Tom Zanussi  <zanussi@us.ibm.com>

        * configure.ac: Add check for relayfs version.
        * configure: Regenerated.
        * stp_check.in: Remove bundled relayfs loading/compilation, add
        check for relay (vs relayfs).

The parser tests won't find relayfs-config.h nor will the pass-5 tests 
find the include file.

-Will
