[Bug-gnulib] lib/pathmax.h

[Jeff Bailey]

I'm concerned that lib/pathmax.h might be limiting on some systems - I
don't know about many others, but certainly i386-pc-gnu doesn't define
pathmax intentionally because there isn't a fixed system-wide limitation
(limitations are implemented per filesystem)

Is pathconf universally available?  If no, I can put together an
implementation of that (basically that just always returns either
PATH_MAX or 255).  Otherwise under the current setup, we're always
limiting systems that could legitly handle more for some filesystems.

Tks,
Jeff Bailey
