strftime(3) for IEEE Std 1003.1-2001 compliance and remove excessive usage of the 'const' qualifier that was neither present in the prototype in the publice header, nor in the local prototype just above the function definition. - Replace the K&R function definition with a ANSI-C one. - Update the prototype of strftime(3) in its manual page.
