compiled in ubuntu dapper, from cvs available in the ekiga webpage, and 
after modifying some source files. Btw, please answer  to 
gnomemeeting-list, not to me directly, so everyone can read it. The 
modifications worked for me, but I can't guarantee you to be completely ok.

1st: compile opal (latest cvs) with -enable--h263avcodec=<dir>, where 
<dir> is the location of libavcodec.so and some header files, you have 
to dload it from voxgratia 
http://www.voxgratia.org/bin/libavcodec-0.4.7-linux.bin.tar.gz
you may need to softlink it to somewhere else, i can't remember now.

2nd: modify ekiga/src/endpoints/manager.cpp
I did it with the latest cvs too. I added this (line 367, inside 
GMManager::SetVideoMediaFormats ())

[...]
OpalMediaFormat rfcmediaFormat ("H.263");
 rfcmediaFormat.SetOptionInteger 
(OpalVideoFormat::EncodingQualityOption, vq);
 rfcmediaFormat.SetOptionBoolean 
(OpalVideoFormat::DynamicVideoQualityOption, TRUE);
 rfcmediaFormat.SetOptionBoolean 
(OpalVideoFormat::AdaptivePacketDelayOption, TRUE);
 rfcmediaFormat.SetOptionInteger (OpalVideoFormat::TargetBitRateOption, 
bitrate * 8 * 1024);

[...]
 OpalMediaFormat::SetRegisteredMediaFormat (rfcmediaFormat);

 if (size == 0) {

   order += "H.261(QCIF)";
   order += "H.261(CIF)";
   order += "H.263";
 }
 else {

   order += "H.263";
   order += "H.261(CIF)";
   order += "H.261(QCIF)";
 }
[...]

And compile ekiga. This way, I've been able to set up connections using 
h.261 with 500 ekiga net and ekiga 2.0.1 on windows, h.263 with windows 
messenger 5.1,  but I'm not 100% sure because my router can't do cone 
nat, so I have nat problems with sending and receiving audio/video. So 
try it, and tell me how it goes for you.
