make delete-old whine: Malformed conditional (${MK_FORTRAN} == no)

Just winding up building today's CURRENT; finished "make installworld"
and started "make delete-old," which whined:

"/usr/src/tools/build/mk/OptionalObsoleteFiles.inc", line 384: Malformed conditional (${MK_FORTRAN} == no)
"/usr/src/Makefile.inc1", line 1285: if-less endif
make: fatal errors encountered -- cannot continue
*** Error code 1

Stop in /usr/src.

Errr... huh?  That file hasn't changed since 10 Oct 2007.  And it's
the same on my work desktop's version of CURRENT (which was last
updated on Sunday, 13 Jan 2008.

The named file (tools/build/mk/OptionalObsoleteFiles.inc) is the only one
where "MK_FORTRAN" shows up anywhere in any of my copies of the tree --
including the one from my work desktop.

(My laptop did the same thing, too.  It's not surprising that they behaved
the same....)

Maybe I'm confused or something.....  :-{

Peace,

I submit that "conspiracy" would be an appropriate collective noun for cats.
