>Environment:
	Noticed on /sparc 1.4T; verified present on /i386 1.6_BETA4.
>Description:
	If mkdep is passed .c filenames beginning with a # character,
	and those files do enough including to generate more than one
	line in .depend (#include <stdio.h> is enough), the resulting
	.depend file produces fatal errors from make, because mkdep
	generates what make interprets as a comment line.
>How-To-Repeat:
	$ mkdir testdir
	$ cd testdir
	$ echo '#include <stdio.h>' > \#foo.c
	$ mkdep \#foo.c
	$ make
	watch make produce errors for the last line of #foo.c's
	dependencies in .depend, saying "Need an operator".
>Fix:
	Make mkdep convert # to \# when writing .depend?  (Doing this
	by hand after mkdep runs produces a .depend make is happy
	with.)  Alternatively, document it and forget it; such files
	are obviously not much used, or the bug would not have lasted
	this long.  (Other characters in .c filenames can cause
	problems; for example, a newline in a .c filename produces
	broken .depend files; a colon does too, though the brokenness
	is subtler.  I do note space and tab get escaped correctly;
	perhaps it's as simple as adding # to that list.)
