I had the --'s in my makedepend call; from the X11R5 makedepend
manpage(which I believe is the correct one for the current release):
- - options - -
If makedepend encounters a double hyphen (- -) in the argument
list, then any unrecognized argument following it will be silently
ignored; a second double hyphen terminates this special treatment.
In this way, makedepend can be made to safely ignore esoteric com-
piler arguments that might normally be found in a CFLAGS make macro
(see the EXAMPLE section above). All options that makedepend
recognizes and appear between the pair of double hyphens are pro-
cessed normally.
Since the -Y is recognized, it is processed "normally" by makedepend, i.e.
it uses it as a substitute for standard include dirs.
