Can't restart debugger with Perl 5.8.8

[MacTommy]

Dear all,

I just installed Perl 5.8.8 (built for MSWin32-x86-multi-thread).

Now if I do perl -d, or debug in Emacs it all runs fine, but if I restart the debugger (option -R), it complains, saying that:

Your vendor has not defined POSIX macro _SC_OPEN_MAX, used at C:\Perl\lib/perl5db.pl line 3296
 at C:\Perl\lib/POSIX.pm line 47
        POSIX::AUTOLOAD() called at C:\Perl\lib/perl5db.pl line 3296
        DB::DB called at myProgram.prl line 5

I haven't got any clue as to what I could do about this..?!?
Any suggestions..?!?

Thanks!

OK, I solved it, just in case anybody is reading this, but I can't say I like the solution.

In perl5db.prl I commented the next lines out (line numbers 3300-3302 in my version):

# if (eval { require POSIX }) {
#    $max_fd = POSIX::sysconf(POSIX::_SC_OPEN_MAX());
# }

Just above there is a line saying:

my $max_fd = 1024; # default if POSIX can't be loaded

so the upshot of it is that this will always be used. Even if you manage to set _SC_OPEN_MAX to a different value, something I couldn't figure out how to accomplish...
