#
# This file demonstrates a parsing bug in make(1) from NetBSD-1.6.2 and
# the current pkgsrc bmake. The make from NetBSD-2.99.15 has been fixed.
#
# The bug is that one of the closing braces is parsed twice -- once as
# terminator for a variable and once as literal character, which is
# appended to PKG_OPTIONS.
PKG_OPTIONS= a b c
.for _o_ in -b -c
_opt_:= ${_o_} # .for variables cannot be used in modifiers
. if !empty(_opt_:M-*)
PKG_OPTIONS:= ${PKG_OPTIONS:N${_opt_:C/-//}} # <-- the bug
. endif
.endfor
PASSED?= no
# /usr/bin/make from NetBSD 2.99.15 or similar
.if !empty(MAKE_VERSION:Mnetbsd-2005*) && ${PKG_OPTIONS} == "a"
