New features in sfind-1.0:


-	New rule file x86_64-linux-gcc.rul allows compilation on AMD-64 systems
	without automake enabled make programs like 'smake'.

-	Better lint rules

-	First real man page created from the Open Group / IEEE standard 
	(with permission).

-	small fixes to make lint happy

-	Fix a but that caused treewalk() not to close the current working directory.
	This did cause 'Too many open files' errors when called with a huge
	number of path arguments like 'sfind * -ls'
