Well, it's ARG_MAX in POSIX, and ARG_MAX is defined as 256K in Darwin, 
512K in FreeBSD, 128K in Linux; _POSIX_ARG_MAX is defined as 4096 on all 
three platforms. Windows may differ too. Anyways, allocating even 128K 
in precious stack space is too much, that's why I suggest to use 
psprintf(). As for checking any hard limit, I don't think it would have 
much value - somehow we got the original command line, thus it is 
supported by the system, so we can just pass it on.
