The following comments pertain to the version of Perl used in FreeBSD,
since this was cited as a FreeBSD 4.0 problem.
This is still true for Perl 5.005_03 in -stable, but it seems to have
been fixed in Perl 5.6.0 in -current. I believe this will be fixed
when Perl 5.6 is MFC'd (btw, FreeBSD developers, FreeBSD Perl gurus,
when/if shall Perl 5.6 be MFC'd? :)
Thus, I believe this is not (anymore) a Perl problem per se, since it
is fixed in the newer versions.
G'luck,
Peter
