	This is my FWIW, but I use the std "/*" and "*/" in C programs and
	often in C++ also.  It's only when I'm [1] lazy, or [2] have severe shoulder 
	pains that I'll use the "//" for comments -- anywhere.  

	This is a bit quirky, but even in my prose I'll use #ifdef/#endif and the
	std C comments.  Very handy for sidebar comments, thoughts, work-arounds or
	"write-around" in early drafts.

	just my $0.02-worth,
