make(1) bug or pkgsrc bug?

[Thomas Klausner <wiz%NetBSD.org@localhost>]

Hi!

Using latest make(1) from last night, mk/find-prefix.mk containing:
28:.for i in ${FIND_PREFIX}
29:.  for varname in ${i:C/=.*$//}
30:.    for pattern in ${i:C/^[^=]*=//}
31:.      if !defined(${varname})
causes the following message for me (in a pbulk, so I don't know
the package):

make: "../../mk/../../mk/find-prefix.mk" line 31: warning: Missing closing 
parenthesis for defined()

pbulk also reports many many lines of:
make: Unclosed substitution for  (/ missing)
and a few
make: Unclosed variable specification for

Bug in pkgsrc or in make(1)?
