# 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.
|
|
|
|

|

|
|
OPTIONS_1:= ${OPTIONS_1:N${_opt_:C/-//}} # <-- the bug
|
|
. endif
|
|

# This is a possible workaround for this bug. It defines an intermediate
|
|
# variable that reduces the complexity of the modifier expression.
