- Moved the locale initialization/cleanup code into constructors and destructors. - The socket cleanup function is now a destructor. - The math cleanup function is now a destructor. - The wildcard cleanup function is now a destructor. - The stdio cleanup function is now a destructor. - The stack extension cleanup function is now a destructor. - The code that cleans up after the program's current directory was changed is now a destructor function. - Moved the initialization/cleanup code for unlink() into constructors and destructors. - Moved the initialization/cleanup code for usergroup.library into constructors and destructors. - Added usleep(), and created wrapper code that both sleep() and usleep() can use. - Added strtoll() and strtoull(), with further changes to <limits.h> and <stdlib.h>. git-svn-id: file:///Users/olsen/Code/migration-svn-zu-git/logical-line-staging/clib2/trunk@14737 87f5fb63-7c3d-0410-a384-fd976d0f7a62
