# Package-settable variables:
#
# GNU_CONFIGURE
#	Whether the package has a GNU-style configure script as the
#	primary means of configuring itself to the platform.
#
#	Possible: yes no
#	Default: undefined
#
# GNU_CONFIGURE_STRICT
#	Whether unknown --enable/--disable/--with/--without options make
#	the package fail immediately.
#
#	Command line options that are unknown for all configure scripts
#	of a package are effectively ignored and should be replaced with
#	their current equivalent (in case they have been renamed), or
#	otherwise be removed.
#
#	This check may incorrectly report unknown options for packages
#	that have multiple configure scripts, when one of these scripts
#	recognizes the option and some other doesn't. To check this, run
#	"bmake show-unknown-configure-options" after the package failed.
#
#	Possible: yes no warn
#	Default: no
#	See also: configure-help show-unknown-configure-options
