So people can check what version of the gst-plugins-base libs they're
building against or linked against.
API: GST_PLUGINS_BASE_VERSION_MAJOR
API: GST_PLUGINS_BASE_VERSION_MINOR
API: GST_PLUGINS_BASE_VERSION_MICRO
API: GST_PLUGINS_BASE_VERSION_NANO
API: GST_CHECK_PLUGINS_BASE_VERSION
API: gst_plugins_base_version()
API: gst_plugins_base_version_string()
cdparanoia now has a .pc file in post-0.10.2 SVN, so use
that to check for cdparanoia before we try all the other
checks. Besides being generally nicer, this may help with
correctly detecting cdparanoia on OSX some day (see #609918).
Orc is not a hard requirement. Things should still compile and
work without orc, but slow fallback code may be used in this
case. Fix up configure to not error out if orc is not installed
and wrap use of orc profiling in audioresample in #ifdefs.
Fixes#620136 some more.
Commit message copied from core's commit from Benjamin Otte:

Apparently gcc warns that GstMiniObject is not castable to
GstEvent/Message/Buffer due to them containing 64bit variables, even
though ARM hackers claim that those only need 4byte alignment. And as
long as gcc behaves that way, this warning is not very useful.
So we'll remove the warning until this problem is fixed.
Fixes#615698
The warnings are:
-Wcast-align
-Winit-self
-Wmissing-include-dirs
-Waddress
-Waggregate-return
-Wno-multichar
-Wnested-externs
No code needed to be fixed.
And fix the resulting compile failures.
I'm sorry about the patch necessary to gstclockoverlay.h but after
talking to Tim we decided we can live with it.
This just replaces every "$ERROR_CFLAGS" usage with a usage of
"$WARNING_CFLAGS $ERROR_CFLAGS" to get the same functionality as
previously.
Actually using that separation will happen later.
If we first check for >= 4.0 the second check for >= 4.6 will just
short-cut since we are using the same prefix for the variables for
both checks, and they've already been set previously. So the examples
requiring >= 4.6 were built even in the >= 4.0 case.
