+compatibility:
+- improved headers for trace/debugging/machine-access
+- stub functions for unsupported thread-related functionality
+
+bug fixes:
+- numerous math bugs (mostly exception flags and excess-precision issues)
+- register clobber error in i386 vsyscall asm (did not affect most callers)
+- various incorrect definitions in mips headers
+- broken dlsym asm on mips

+
+arch-specific bugs fixed:
