I try to generate the Luyten release of a library combination with the current
compiler again also on my openSUSE Tumbleweed system.

I wonder about the following results here.

elfring@Sonne:~/Projekte/OpalVoip/OPAL/3.10.10> ./configure
--disable-libavcodec
...
checking PTLIB has expat... yes
checking PTLIB has video... no
...

Excerpt from ~/Projekte/OpalVoip/OPAL/3.10.10/config.log:
...

I find it strange that the reduced command parameter set (deletion of
duplicated options and preprocessor symbols) shows differences in the error
messages.
