There are two bugs in the configure step of the gxine and SDL_mixer.

For gxine, the new version does not include any js code any more. 
Instead it looks for the javascript implementation of Mozilla. But doing 
so, it search only for Mozilla or Firefox, and not Seamonkey. Wherefore 
it is impossible to configure Gxine when one is using Seamonkey instead 
of Firefox or Mozilla.

For SDL_Mixer, there is a strange bug in a C embedded code within 
configure that checks for the SDL version. As I am completely foreign to 
the SH family of shells, if someone could have a look, that'd be nice, 
otherwise I'll try to fix the bug myself, but I don't even know how to 
put the fix back into the mainstream.
