Hi. I asked for clarification of whether this patch was correct.
In particular, I asked whether the patch was masking a legitimate test
failure and why the test should be skipped on hurd.

I'll admit that given Debian's approach to the i386 port, I'm finding
hurd-i386 less and less compelling as a port as well.
I'm happy to take clean patches that do not mask problems, but my bar is
going to be higher than it was years ago.

Source: pam

Hi,

pam FTBFS on hurd-i386 (built in the past, last successful build was
1.4.0-10).

Attached are four files:
- no_PATH_MAX_on_hurd rewritten to cope with that many tests use
PATH_MAX.
- modules_pam_limits_pam_limits.c.diff embedding code with #ifdef
__linux__ that only works on Linux.
- modules_pam_nologin_tst-pam_nologin-retval.c.diff disabling two
subtests failing on GNU/Hurd.
- debian_libpam-modules-bin.install.hurd-i386.patch creating an install
file for Hurd excluding two systemd-specific files not needed.


Thanks!




Description: define PATH_MAX for compatibility when it's not already set
 Some platforms, such as the Hurd, don't set PATH_MAX.  Set a reasonable
 default value in this case.
