Re: On PATH_MAX

[Alfred M\. Szmidt]

   [...] A reasonable limit is necessary.

Being _ABLE_ to set a limit is necessary.  But setting a globally
static limit like PATH_MAX is not that solution, if you increase
PATH_MAX then you will need to recompile the whole system, and one
program might not work on a different version of the system; this
won't happen if you just allocate the memory for the filename.

As I suggested, provide a way to limit resources.
