When the POSIX pthreads library for w32 release 2-2-0
(http://sources.redhat.com/pthreads-win32/) is compiled with VC++6
then it compiles and passes all the benchmark tests in the subdirectory "tests".
Also, VC++ 2005 beta 1 compiles the tests fine, but here the following
tests fail in execution:

#   semaphore1.pass \
#   condvar2.pass \
#   condvar2_1.pass  \
#   mutex8.pass \
#   mutex8n.pass \
#   mutex8e.pass \
#   mutex8r.pass  \
#   condvar3.pass  \
#   condvar3_1.pass  \
#   condvar3_2.pass \
#   condvar3_3.pass  \
#   condvar4.pass  \
#   condvar5.pass  \
#   condvar6.pass  \
#   condvar7.pass  \
#   condvar8.pass  \
#   condvar9.pass  \
#   rwlock7.pass  \
#   rwlock8.pass  \
#   rwlock2_t.pass  \
#   rwlock3_t.pass \
#   rwlock4_t.pass  \
#   rwlock5_t.pass  \
#   rwlock6_t.pass  \
#   rwlock6_t2.pass  \
#   spin4.pass  \

Why are there such differences in execution of the generated code
between VC++6 and VC++2005 ? Is this due to bugs in the beta1,
or is this the result of general differences between the two products?
Are there any compiler/linker switches for backwards "compatibility" to VC++6?
