m4 @1.4.19_1: fails on Leopard: /confdir-14B---: No space left on device

[kencu (Ken)]

Interestingly, Tiger installed this without any trouble.

I also tried in trace mode, just in case, but same error. Disabling parallel builds didn't fix it either.

I cleaned and attempted it again with the same issue. I'm thinking it must be something broken about that particular installation.

1.4.19_1 just installed fine on my other Tiger system, a G4 iBook.

For reasons I am not presently able to explain, m4 installed without trouble on the same Leopard system today.

All the other ports had finished updating. I installed it from a git repo rather than the usual default rsync repo. Otherwise I can't see anything that was changed.

My favourite kind of problem: intermittent, and inexplicable :>

Yuk -- just saw this again on another system, and no combo of disabling parallel builds, etc, fixed it.

The issue is coming, it seems, from a test in this file m4/getcwd-abort-bug.m4 that makes it's way into the configure script. I didn't spend hours on it, but it looks like they are looking for some kind of bug in libc on certain versions of linux, that shows up when PATH_MAX < getpagesize ();.

To get around it, I did this:

$ diff -u configure.old configure
--- configure.old	2021-06-05 17:36:56.000000000 -0700
+++ configure	2021-06-05 18:48:13.000000000 -0700

 #else
   int bug_possible = 0;
 #endif
-  if (! bug_possible)
+  if (1)
     return 0;
 
   cwd = getcwd (NULL, 0);

to abort running of the test.

I have no idea of this is a proper fix for this issue. I already tried looking around upstream for the Tiger RegNames issue, and I can't figure out where to even see the commit tree to m4, much less sort out how on Earth they would like you to go about asking a question.

And -- so far this only shows up for me on Leopard, so it's pretty hard to burn my limited cred on reporting Leopard bugs :>

If we want this teeny little fix as a patch in m4 to apply on Leopard (and less?) I'm happy to throw that 10 second patch into the port.
