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.
official modular Xorg release of libXt.
This is so the xt.pc pkg-config file will have "appdefaultdir"
defined.
(I am guessing I am the only person in the pkgsrc world with this problem
since I have systems with libXt from xlibs days.)
This is the X Toolkit Intrinsics library. Xt Intrinsics is a library
of C routines (based on Xlib) used for designing user interfaces
with widgets. It also provides functions for handling events,
initializing windows, and interpreting resource files.
This is from the modular X.org project.
