Date Modules Changes
+2011-09-12 fchdir This module no longer overrides the functions
+ opendir() and closedir(), unless the modules
+ 'opendir' and 'closedir' are in use, respectively.
+ If you use opendir(), please use module 'opendir'.
+ If you use closedir(), please use module 'closedir'.
+
2011-08-04 pathmax The header file "pathmax.h" no longer defines
PATH_MAX on GNU/Hurd. Please use one of the methods
listed in pathmax.h to ensure your package is
