perl.exe is called directly, by the spawnvpe() call.
Apparently, it gets this in its argv:

   argv[0] = C:/tl
   argv[1] = test/2008/tlpkg/tlperl/bin/perl.exe
   argv[2] = c:/tl
   argv[3] = test/2008/texmf/scripts/texlive/generate-updmap.pl

And then it will attempt to load a perl script by the name
it finds in argv[1]. To me, that sounds like a runtime library
issue (but it could be 'my' msvcrt, it is not necessarily perl's).

Best wishes,
