-Fix deactivation of gtk-doc
-
-The tarball contains the Makefile for building documentation with gtk-doc,
-Unfortunately the AM_CONDITIONAL variable is not the correct one, which
-results in an error when running autoreconf.
-
-This patch fixes this issue.

-Subject: [PATCH] GLib: implement GMutex natively on Linux
-
-If we have futex(2) then we can implement GMutex natively and gain a
-substantial performance increase (vs. using pthreads).
-
-This also avoids the need to allocate an extra structure in memory when
-using GMutex or GCond: we can use the structure directly.
-
-The main reason for the increase in performance is that our
-implementation can be made more simple: we don't need to support the
-array of options on pthread_mutex_t (which includes the possibility, for
-example, of being recursive).
-
-The result is a ~30% improvement in uncontended cases and a much larger
-increase (3 to 4 times) in contended cases for a simple testcase.
