An "-R" option has been added to the "sccs" command to support recursive operation on directory hierarchies. A manual page has been added for the "sccs" command. "make" now supports the GNU syntax for conditional macros ("target: variable=value"), parse-time conditionals ("ifeq (arg1, arg2)"), and functions ("$(function arguments)"). Text functions, file name functions, the shell function, and warning/error message functions are supplied. "make" can now retrieve data from SCCS s.files in the current directory.
