- Subject: Re: What is the main change that makes Lua uses stack space over versions

Actually an int is always 4 bytes (leaving away old 16 bit platforms like for MS-DOS or Windows 3.x). A long can be 8 byte on Unix 64-bit platforms but will be always 4 byte under Windows even on 64-bit platforms.
