This minor maintenance release cleans up the build configuration scripts,
including making them compatible with automake-1.13, which errors out on
the old AM_CONFIG_HEADER macro.
Alan Coopersmith (2):
Strip trailing whitespace
libXcomposite 0.4.4
Gaetan Nadon (3):
config: remove AC_PROG_CC as it overrides AC_PROG_C_C99
config: replace deprecated AM_CONFIG_HEADER with AC_CONFIG_HEADERS
config: comment, minor upgrade, quote and layout configure.ac
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.
