configure.ac: use AC_C_INLINE

Browse source 
Original commit message from CVS:
2004-01-30  Benjamin Otte  <in7y118@public.uni-hamburg.de>

* configure.ac:
use AC_C_INLINE
* configure.ac:
* ext/Makefile.am:
* ext/theora/Makefile.am:
* ext/theora/theoradec.c:
add theora video decoder. Does just do simple decoding for now and
has been tested against Theora cvs only.
* ext/vorbis/vorbisdec.c: (vorbis_dec_event):
always reset packetno on DISCONT
