There's also > > #define __IGNORE_alarm > #define __IGNORE_creat Tell you what, I wouldn't mind if the following ones were actually implemented as syscalls in the kernel on Alpha: > #define __IGNORE_getegid > #define __IGNORE_geteuid > #define __IGNORE_getgid > #define __IGNORE_getpid > #define __IGNORE_getppid > #define __IGNORE_getuid There's a growing number of software packages that are deciding to sideskip glibc and call these syscalls directly. Supporting OSF's C ABI incompliant getxpid, etc., in such packages is not easy and rather intrusive. Cheers, Michael.
