This minor maintenance release mostly provides the usual collection of
janitorial cleanups and build configuration improvements.
It also changes the installation path for the pkg-config xbitmaps.pc from
$(libdir) to $(datadir), as no libraries or compiled code are found via
this pkg-config file, only platform-independent image files (which double
as C source code headers that programs may #include at compile time).
Create COPYING file from notice in terminal & X11R6.6 release notes
Move black6 & box6 bitmaps from xmh module
Migrate to xorg macros 1.3 & XORG_DEFAULT_OPTIONS
Add *~ to .gitignore to skip patch/emacs droppings
Replace static ChangeLog with dist-hook to generate from git log
add .gitignore
Correct make distcheck.
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.
