Re: new module 'sys_wait'

[Bruno Haible]

And with this patch, the 'wait-process' module makes use of the substituted
<sys/wait.h>.

2008-10-19  Bruno Haible  <address@hidden>

        * lib/wait-process.c: Include simply <sys/wait.h>.
        (waitpid, WTERMSIG, WCOREDUMP, WEXITSTATUS, WIFSIGNALED, WIFEXITED,
        WIFSTOPPED): Remove fallback definitions.
        * modules/wait-process (Depends-on): Add sys_wait.
