Only it strikes me that it might be plugging the wrong hole. I.e., that the real issue is that somehow we're not including sys/wait.h in all cases. Would it perchance also work to have #ifdef HAVE_SYS_WAIT_H #include <sys/wait.h> #endif somewhere at the top of the files that use the two macros (sysutils.c and sys-unix.c AFAICS). "&& defined(WEXITSTATUS)" probably won't break anything that wasn't already broken, but it does insert a default definition that could conflict with the one intended for the OS (that's what include files and macros are for, after all). -- Peter Dalgaard Center for Statistics, Copenhagen Business School Phone: (+45)38153501 Email: pd....@cbs.dk Priv: pda...@gmail.com ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
