Continuing this theme ...

On Linux one has in /usr/include/setjmp.h an #if 
muddle that results in

#define setjmp(b) sigsetjmp(b,0)

or

#define setjmp(b) sigsetjmp(b,1)

So it is tricky to test.

Can you tell me if passing 0 to sigsetjmp(b,0) is significantly slower
than setjmp() for you ? (Solaris, OS/2)
