Here is a sample code that shows the bug. It runs fine on my Linux box
and hangs on a Ultra5 (sparc-sun-solaris2.7)

[snip]

Doesn’t hang on Solaris2.6 (Ultra1). Does solaris 2.7 implement recursive
mutexes? 2.6 lacks them, so the generic implementation is used.

For some reason the subthread does not appear to run. I’ll check further.

solaris 2.7 does implement recursive mutexes… badly
A workaround to this is to compile SDL with the
-DPTHREAD_NO_RECURSIVE_MUTEX and it works just fine (thus SMPEG works
fine too).

Is there a way to determine if the recursive mutexen are broken? Then
we should include it in the configure script to do this automatically

Thanks, I’ve fixed this in CVS.

See ya!

I uh, just define it for Solaris.
