>Description:
sys/wait.h #defines WSTOPPED _WSTOPPED which is 0177

This is a bug as WSTOPPED has been introduced as a waitid() flag bit
in 1989 and is standardized in POSIX as a better name for WUNTRACED.


>How-To-Repeat:
Compile standard compliant sources that make use of WSTOPPED and see that the behavior of the wait*() calls that use flags is not as expected.
>Fix:
Remove the illegal #define and replace it by the standard compliant definition:

#define WSTOPPED WUNTRACED
