$xgcc -v

The manner is which Java is being checked _seems_ completely different. I'm not
a Java expert, in fact I only know a little about it - shouldn't Java be
(identical) _independant_ of the platform ?
Notice the above error for the "i686-pc-cygwin" target: "gcjh: PR9577: no such
class".
If I type this (cygwin), I get this ...
$cd /cygdrive/c/gcc-4_2-branch-build-9c/i686-pc-cygwin/libjava/testsuite
$/cygdrive/c/gcc-4_2-branch-build-9c/gcc/gcjh PR9577
gcjh: PR9577: no such class
$ /cygdrive/c/gcc-4_2-branch-build-9c/gcc/gcjh --classpath . PR9577
(no error message)
$
If I set classpath to point to the directory that contains the "PR9577.class"
file, then gcjh runs without error. This problem with the testsuite on the
Cygwin target creates many errors in the libjava section of my "make -i check"
tests that do not occur on the Linux target.
I notice that the Linux .log shows that the test environment sets up
"set_ld_library_path_env_vars" but that the Cygwin version of the tests do NOT.
I don't know that gcjh would need the "ld path" to be set (though other parts
of the test might need this), this _could_ be another problem.
Perhaps the testsuite needs to set a CLASSPATH environment variable that is not
shown in the .log files. If I learnt java I could be of more help :) .
During the _build_ of gcc (not the "make -i check") gcjh uses these sort of
commands ("-d . -classpath '' -bootclasspath classpath/lib") and there are no
errors; but during check testing it is ran with no parameters (and complains
"no such class"):
make[3]: Entering directory
`/cygdrive/c/gcc-4_2-branch-build-9c/i686-pc-cygwin/libjava'

I am not sufficiently familiar with Java to suggest a "proper" fix. I don't
want to monkey with something that I don't understand - just reporting the
tests are failing and the manner in which they run seems inconsistant.
When I run "make -i check" I get this result for Cygwin:
=== libjava Summary ===
# of expected passes 5325
# of unexpected failures 832
# of expected failures 12
# of untested testcases 823
A "reasonable" result (since 4.2.0 is not a release yet), but too many
failures.
This problem with the testsuite compilation is also the cause of so many
"untested testcases".
When I run "make -i check" I get this result for Linux:
=== libjava Summary ===
# of expected passes 6984
# of unexpected failures 22
# of expected failures 12
# of untested testcases 8
A "reasonable" result (last week there were no failures).
I'll enclose the Cygwin libjava.log.
