Yep, the example with the delete( $ENV   ...) shows clearly that there
is a problem with forked/spawned processes which should be resolved.

In the first place I would be glad if someone (petdance?) could fix TH
for Cygwin so that it works to install modules (well, to run the test 
suites) on Cygwin.

I wonder why I got no errors when running the testsuite during the build
of perl-5.8.7, maybe some more tests are needed to cover this issue?
