linux 64bit? Most likely in it a problem.
Also, if I do a make clean && make in that directory it doesn't do anything: -
# make make[1]: Entering directory `/root/dshow/xine-lib-1.2/src/libw32dll' make[1]: Nothing to be done for `all-am'. make[1]: Leaving directory `/root/dshow/xine-lib-1.2/src/libw32dll'
Could this be the problem?
