Wrong CLASSPATH is set during libjava tests

[Kaz Kojima]

Hi,

I've got huge number of failures during libjava testsuite on
my FC4 box.  It started to fail after the patch

r115097 | fitzsim | 2006-07-01 03:31:48 +0900 (Sat, 01 Jul 2006) | 18 lines

I could find

jar file is /exp/ldroot/dodes/i686-gcc-orig/i686-pc-linux-gnu/libjava/testsuite/../libgcj-4.2.0.jar /exp/ldroot/dodes/i686-gcc-orig/i686-pc-linux-gnu/libjava/testsuite/../libgcj-tools-4.2.0.jar

and

CLASSPATH is .:/exp/ldroot/dodes/ORIG/trunk/libjava/testsuite/libjava.cni:/exp/ldroot/dodes/i686-gcc-orig/i686-pc-linux-gnu/libjava/testsuite:/exp/ldroot/dodes/i686-gcc-orig/i686-pc-linux-gnu/libjava/testsuite/../libgcj-4.2.0.jar /exp/ldroot/dodes/i686-gcc-orig/i686-pc-linux-gnu/libjava/testsuite/../libgcj-tools-4.2.0.jar

lines in my libjava.log file with the verbose option and the appended
patch against libjava.exp works for me.  After r115097, $libgcj_jar
is set to the list of 2 jar files and it seems that the additional
flatten operation is needed.  I could be wrong about that, though.
It looks almost testresults sent to gcc-testresults have no problem
on libjava except the results from the automatic regression tester on
powerpc-apple-darwin8.5.0.
So I suspect that something is wrong in my local environment.
Does anyone see this problem?  The version of DejaGnu I'm using is

  Expect version is       5.43.0
  Tcl version is          8.4
  Framework version is    1.4.4

Regards,
