Applied. I now see that coreutils/src/su.c has this: /* Hide any system prototype for getusershell. This is necessary because some Cray systems have a conflicting prototype (returning `int') in <unistd.h>. */ #define getusershell _getusershell_sys_proto_ #include "system.h" #include "getpass.h" #undef getusershell If Cray systems are still a portability target, the current idiom for this kind of problem is to add #define getusershell rpl_getusershell in unistd.in.h.
