I've noticed this on a couple of occasions myself. The warnings come 
because WEXITSTATUS and WIFEXITED aren't defined in config.h when they 
are parsed there, but there are no conditionals around them in 
sys/wait.h (which is where they actually should be defined). On some 
systems they are duplicated in stdlib.h (FC3 does this, Openwall does 
not). Where they are not, one gets two three-line warnings for every 
C-file compiled. I imagine it can be a bit worrying for those who don't 
know what it means.

The neatest solution is to move the conditional definition of system 
macros to the end of config.h. That way the system headers are 
guaranteed to have the first shot at defining them.
