Subject: [Bug c/21706] New: MAXPATHLEN usage in [gcc]/gcc/tlink.c

Please do not use MAXPATHLEN, it is a arbitrary limit, and is not
defined on GNU.  Currently gcc 4.0.0 is unbuildable on GNU since
[gcc]/gcc/tlink.c assumes that MAXPATHLEN is defined.  Please do not
use these kind of limits in GNU programs.

Suggested fix is to declare initial_cwd as:

  char *initial_cwd;

and then instead of doing:

  getcwd (initial_cwd, sizeof (initial_cwd));

do:

  initial_cwd = getcwd (NULL, 0);

Note: getcwd (NULL, 0) is a GNU extention, and might not be available
on non-GNU platforms.  (End of Note)

Sorry for not supplying a patch, happy hacking.
