	Uses ISC/IBM freely redistributable Base64 routines
	SHA1 support requires external SHA1 routines

* POSIX RegEx is not currently included in the distribution, however
	we will probably add Henry Spencer's REGEX library soon.
* ACL Group functionality is also included in this merge!

Fixed Dependency Generation not to mess with Make-templates.
	side effect: depends are not carried forward after "make makefiles"

Changed type of lconn_lastused to time_t.
Added include <time.h> were needed.

and setting of variables from Make-platform with defaults in Make-common.
