FreeBSD-i386, perl

[bsam]

I've got an error at FreeBSD-i386:
-----
zmwatch[2097].ERR [Shared data size conflict in shared_data for monitor Monitor-1, expected 328, got 316]
-----

It is caused by the code at scripts/ZoneMinder/lib/ZoneMinder/Memory.pm.in (line 130):[code]our $arch = int(3.2*length(~0));[/code]
Here is what we have at FreeBSD:
-----
% perl -e 'print int(3.2*length(~0)),"\n"'
64
% perl -V

One can see that perl is compiled with USE_64_BIT_INT option (it's a gefault option). That's why the first test is 64.
I patch the FreeBSD-i386 port to use the value of 32, but that's a hack imo. I'm sure how to do the right thing. Should we use intsize or ptrsize to calculate $arch and/or $native?

The best thing is to use a uniform shared memory size and layout. This way the offsets and the size will be identical for every platform and will allow 32bit and 64bit to co-exist. e.g. 32bit perl and 64bit ZoneMinder. I did this in the patch in my thread, feel free to copy\use.

Thanks for your patch and suggestion!
However I'm not sure if I can cherry pick needed parts from your patch.
Let's hope your changes will find their way to the next release.
