Subject: [PATCH] maint: don't use gnulib's pathmax module; define PATH_MAX if
 needed

* bootstrap.conf (gnulib_modules): Remove pathmax.
* src/system.h: Don't include "pathmax.h".
(PATH_MAX) [!PATH_MAX]: Define to 8192.  Defining it to a constant
is preferable to using a definition from pathmax.h that might expand
to pathconf ("/", _PC_PATH_MAX). Prompted by discussion leading to:
