I just found my 1991 copy of ORA's POSIX Programmer's Guide. It says
specifically:
-----------------------
[...]
_PC_PATH_MAX The maximum lenght of a relative pathname when this direc-
tory is the working directory; that is, the number of
characters that may be appended to path and still have a
valid pathname.
[...]
Notes:
The value returned by _PC_PATH_MAX is not useful for allocating storage.
Files with paths longer than _PC_PATH_MAX may exist.
-----------------------
So I think pathconf() is of approximately zero use to zsh, at least for
_PC_PATH_MAX, and we should just rip zpathmax() out again. I apologize
for helping lead us down this rathole.
