+	- ev.h wasn't valid C++ anymore, which tripped compilers other than
+          clang, msvc or gcc (analyzed by Raphael 'kena' Poss). Unfortunately,
+          C++ doesn't support typedefs for function pointers fully, so the affected
+          declarations have to spell out the types each time.

+        - (ecb) support m68k, m88k and sh (patch by Miod Vallat).
+        - use a reasonable fallback for EV_NSIG instead of erroring out
+          when we can't detect the signal set size.
+        - in the absence of autoconf, do not use the clock syscall
+          on glibc >= 2.17 (avoids the syscall AND -lrt on systems
+          doing clock_gettime in userspace).
+        - ensure extern "C" function pointers are used for externally-visible
+          loop callbacks (not watcher callbacks yet).
+        - (ecb) work around memory barriers and volatile apparently both being
+          broken in visual studio 2008 and later (analysed and patch by Nicolas Noble).
