Oops, sorry about the empty reply.  I had a problem similar to this with
locally scoped environment variables, but could only get it to occur on
Cygwin with Windows NT (see RT #30952).  Upon some examination, it
appears that the two problems are the same.  The attempted workaround in
RT #30952 does undef the environment variable as far as Perl is
concerned, but it does seem to leave it empty in the environment.
