Hello monks,
i used readline::rl_basic_commands as only way to have autocompletion working in win32. if i remember correctly i found the mention here.

I had used this sub in some programs based on various Strawberry distros without any problem.

Now i have a new program i would like to run on Win32 as in Linux and it uses only core modules.
I developped on my strawberry Perl but when tried on the Linux box it complains about that missing sub: 
Undefined subroutine &readline::rl_basic_commands called at...

So i changed the call in something like: 
if (exists &readline::rl_basic_commands){&readline::rl_basic_commands(
+keys %cmds);}

Now on Linux works (without autocompletion), but using that syntax on win32 made the first time intialization of available commands not working. The following working example shows my problem: 
#!perl
use strict;
use warnings;
use Term::ReadLine;
$ENV{TERM}=undef;
my $term = Term::ReadLine->new('xxx');

my %cmds = (a=>1,b=>2);

   # THIS WORKS &readline::rl_basic_commands(keys %cmds);
   # THE FOLLOWING CHECK DOES NOT WORK
   if (exists &readline::rl_basic_commands){print "BEFORE WHILE EXISTS
+\n"; &readline::rl_basic_commands(keys %cmds);}

while ( defined ( $_ = $term->readline( '>') ) ) {
     print "$_\n";
}
continue{
   # THIS CHECK WORKS INDEED!
   if (exists &readline::rl_basic_commands){print "IN CONTINUE EXISTS\
+n"; &readline::rl_basic_commands(keys %cmds);}
}

Where and when the sub is defined?
There is safe way to deal with it?
There is a way have it working on both Linux and Win32, even in the sad case without autocompletion?

Thanks for the attention.
