>Description:
	There are more than 5000 warnings issued during "make buildworld".
Some of them are false positives, but some of them are sign of true errors.

	Nobody is upset by warnings due it's amount, so some errors remain
uncorrected.

	I want to cleanup the code-base from warnings, so warnings will
become "attention mark" again.

usr.sbin/pppctl/pppctl.c:368: warning: 'fd' might be used uninitialized in this function
'fd' is initialized with no exception, so turn-off warning only

>How-To-Repeat:
	N/A
