[PATCH] for PR driver/21706 -- MAXPATHLEN usage in [gcc]/gcc/tlink.c


Hello!

It has already been posted months before, but here it is again.  It is
not mandatory for a system to define MAXPATHLEN (GNU/Hurd doesn't do, for
one example) and we can do better nevertheless.  Am I allowed to say
``I'm going to commit this if no one objects within a week.''?

2007-08-01  Samuel Thibault  <samuel.thibault@ens-lyon.org>

	* tlink.c: Include "libiberty.h"
	(initial_cwd): Change type into char *.
	(tlink_init): Call getpwd instead of getcwd.
