I really dont like this. as Trointhiel wrote, this will be a
dublication of a lot of options. Better would be something like
--try-option that makes some tests and enables it if possible for those
few options that actualy have different behaviours for try and force.
BTW: dont think that arpi and gabu were the only ones who opposed the
--enable policy change.

and --try-all, --enable-means-force, --enable-means-try
then we could make --try-all --enable-means-try default and all users 
would be happy. Developers and packager can still use --try-all
--enable-means-force resp --disable-all --enable-means-force.
A config file for ./configure would be also nice :)

sounds interesting. can you elaborate that a bit more ?

Yes.  btdt.
Beside our configure script is far from being perfect and as long as it
is not perfect i want to have maximum control over it.

I especialy dont want to have more work while doing bug hunting. It
needs enough as it is.
BTW: you should use ccache, it speeds the compilation up by a factor of
5 on a normal day, or 20 if very little changed. (w/o ccache i would
have given up working on mplayer a long time ago)
