- Added asctime_r(), ctime_r(), gmtime_r(), localtime_r() and strtok_r(). - Added stubs for the Rexx Variables Interface code that used to be part of amiga.lib. While comparable functionality is available in rexxsyslib.library V45, the new stubs might be helpful during porting. Care must be taken since these functions don't work exactly like the originals. - Integrated strlcpy() and strlcat() which are intended to be safer replacements for strncpy() and strncat(). - The program's task priority is now configurable through an external variable '__priority'. - The process name to be used when detaching can be configured through the new '__process_name' variable. - The minimum required operating system version can be configured through the new '__minimum_os_lib_version' variable; a matching error message can be provided through the new '__minimum_os_lib_error' variable. - The default console window specification can be overriden through the new '__stdio_window_specification' variable. - The socket initialization code did not set up a reference to the 'h_errno' variable correctly. This had the effect of making name and address resolution errors trash the 'errno' variable instead and leaving 'h_errno' always set to 0. Fixed. - For sockets, ioctl() and fcntl() now interact on the FIONBIO/FIOASYNC requests (ioctl) and the O_NOBLOCK/O_ASYNC flags (fcntl). - popen() now accepts "rb" and "wb" as mode parameters. However, "r+", "w+" and variants thereof are still unsupported due to the unidirectional pipe support in the standard "PIPE:" device. git-svn-id: file:///Users/olsen/Code/migration-svn-zu-git/logical-line-staging/clib2/trunk@14777 87f5fb63-7c3d-0410-a384-fd976d0f7a62
