Warnings removal (linuxthreads/*pt-machine.h)

[Andreas Jaeger]

Compiling glibc gives lots of these warnings:

../linuxthreads/sysdeps/i386/i686/pt-machine.h:36: warning: no previous prototype for `testandset'
../linuxthreads/sysdeps/i386/i686/pt-machine.h:54: warning: no previous prototype for `__compare_and_swap'

What do you think of the appended patch?  

Btw. should testandset return long int like alpha,ia64,mips or int
like arm,hppa,i386,m68k,s390,sh ?  Depending on the answer some
prototypes need be changed.  IMO it should be long int.

	* internals.h: Add prototypes for testandset and
	__compare_and_swap to shut up gcc warnings.
