what does it exactly mean? as mplayer is single thread program, it
should work, but it isn't really reentrant (uses lots of global vars)

btw. are you intereste din rewritting ./configure script to use functions
and also some cleanup... i've collected suggested changes earlier in a mail.
current one is bigger and bigger every day and it's messy. and the messages
printe dby it are sometimes confusing or simply bad (see c++ test results
for example)
