Hi monks,

for a module which uses a lot of bitwise operations I want to have it portable, thus test for 64 or 32 bit support, which seems to work like this:

helmut@raspberry2 ~ $ perl -e  'print length(pack('j', -1))*8,"\n";'
64

Will this work? I cannot test it, because even my raspberries have 64int-Perls.

In reply to reliably test integer size for portable bit-fiddling? by wollmers
