There's a block of code that is #ifdef __sun__ in threadimpl.h that
breaks Solaris. I was just in the process of preparing a diff when I
was distracted by other things.

In particular, this block is unnecessary and harmful:

#if defined(__sun__)
#	define mcontext libthread_mcontext
#	define mcontext_t libthread_mcontext_t
#	define ucontext libthread_ucontext
#	define ucontext_t libthread_ucontext_t
#	include "sparc-ucontext.h"
#endif

Having eliminated that, however, it's working well for me.
