Perl uses whatever command shell that its C compiler uses.  If that 
command shell happens to be a Bourne shell, then the whole pipe sequence 
works (subject to availability of sed, sort, and uniq but that is pretty 
much a freebie on systems with Bourne shells) and should be used to 
avoid the completely unnecessary risk of breaking pre-existing 
platforms.  (I defer to those who actually have seniority regarding 
whether that risk is completely unnecessary, but that is what dictated 
my strategy in implementing this originally.)

If the C command shell is cmd.exe or command.com (which is true for 
ActivePerl, Strawberry Perl, and Perl built from tarball using MingW32, 
but *not* the binary package of Perl distributed by the MingW project), 
the pipe from nm to sed fails.  Nothing is detected regardless of the 
results from nm in this case.
