>Description:

	While it is nice to try to make people's systems more secure, it
	isn't polite to cause malfunctions in pursuit of this endevour.

	The 'sh: warning: running as root with dot in PATH' warning message
	is emmitted even when the output of the script is being captured
	by another program.  This breaks things.

	While it isn't possible to truely know when it is safe to print
	random garbage on the screen, there is a pretty easy test.

>How-To-Repeat:

	As an example:
	Try to run trn's Configure with as root with . in your path.

>Fix:

	guard the printf with a call to isatty(3).


	A more appropriate check would be whether or not the shell is
	interactive.  However, I've chosen to simply removing the warning
	completely.  - mycroft
