bsnes and static libraries

Hi, as you might already know, I submitted bsnes for review a while ago [1]. One of the issues pointed out is that it uses its own copies of system libs - ntsc filter, zip and jma, possibly others. I did contact the author a while ago (regarding zip), and he said that local zip copy is needed for windows. I guess he does not really care. On the other hand, I think that if the usage of system-wide libs could be conditionalised in an easy and transparent way, he would not mind a patch. I can't prepare it myself (I cannot code), but if someone prepares such patch, I am willing to push it upstream - otherwise we cannot use it since the license is quite restrictive. We can as well ignore the problem and leave the situation as is. What do you think? Julian [1] https://bugzilla.rpmfusion.org/show_bug.cgi?id=15
