Does anyone know what can be causing this? My guess would be cc, but dont quote me on that :) Am I the only one with this problem? Perhaps some people with perl on their 386bsd boxes (patchlevel 36 is what im using) could try it? Its really annoying, cause I cant be sure a script written on another machine will work, cause it may rely on integers being truncated. And yes..ive already had to change scripts cause of it. Hmm..actually..i'll try and compile perl with gcc in a sec :) cor -- | cor@hacktic.nl | Hack-Tic System Management | +31-20-6001480-3 (VMB) | | -------------------------------------------------------------------------| | ######### Signature Virus Running.
