S_IRUSR and S_IWUSR are defined in <sys/stat.h> on DragonFly, but the
conftest for the Cache Server wasn't pulling that header in. After
patching the conftest, the package builds normally. There was no need
to patch the source itself, so it was a bad test.
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.
This package is based on wip/evas, originally packaged by airhead AT
users.sf.net and maintained by YazzY (yazzy AT yazzy.org).
Evas is a clean display canvas API for several target display systems
that can draw anti-aliased text, smooth super and sub-sampled scaled
images, alpha-blend objects, and more.
