XMMS 1.1.2 plugin on FreeBSD
libmusepack 0.9.6 and xmms plugin 1.1.1 had no problems workin on FreeBSD 5.3 but then came libmusepack 1.1 and a new xmms plugin version 1.1.2.

There is a port for libmusepack that is the latest 1.1 (more information but the xmms plugin in the ports tree is REALLY old Well I had used xmms plugin with libmusepack 0.9.6 and xmms plugin 1.1 and now that there was a new libmusepack I was off to test xmms plugin 1.1.2 and it did not work. After some debugging it was clear that the problem was threading related, so off I was chatting with my friend who has experiance with FreeBSD and threading issues. So long story short, this patch will enable xmms plugin 1.1.2 be used on Freebsd 5.3 (tested). It fixes iconv problems with bad type casting and increased the stack size (the FORCED_THREAD_STACKSIZE number is not based on any scientific methods, it just works with this ... I bet it will work with a smaller stack size but I did not test when the size gets too small).

To get this to work just install libmusepack from the ports tree and then extract the source for xmms plugin 1.1.2, go to xmms-musepack-1.1.2/src/ copy this patch with some filename there, patch it with "patch <filename" and do a "./configure CFLAGS=-I/usr/local/include" in xmms-musepack-1.1.2/ then "make" and copy xmms-musepack-1.1.2/src/.libs/ to /usr/X11R6/lib/xmms/Input

Thanks for the patch.
