Looks good, thanks.  However, could you please check for "__restrict"
before "__restrict__"?  GCC supports either spelling, but "__restrict"
is shorter and older DEC Alpha C compilers support only "__restrict".
The handwritten "configure" script for MPlayer
<http://www.mplayerhq.hu> checks for "__restrict" first, so this
should be reliable.

Also, please check for "_Restrict" as well.  That is the only spelling
supported by Sun WorkShop 6 update 2 C.

Aren't the other AC_C_ macros in that camp too?

Perhaps we should use AC_CONLY_ as a prefix for macros that are no
good for C++.  This reminds me of the story of the man whose full name
was "R B Jones", and whose paychecks always read "RONLY BONLY JONES"
-- but I digress....
