This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.
changes:
-Port to gtk 2.12 tooltips API
-Now first toplevel in project automatically shows up in the workspace
-Project no longer allows duplicate widget names
-bugfixes
-translation updates
Stop lying and drop maintainership of these packages. I have not
maintained them for a very long time already, so leave room for
fresh blood to take over them.
