-** This program checks to see if your version of setreuid works.
-** Compile it, make it setuid root, and run it as yourself (NOT as
-** root). If it won't compile or outputs any MAYDAY messages, don't
-** define HASSETREUID in conf.h.
-**
-** Compilation is trivial -- just "cc t_setreuid.c". Make it setuid,
-** root and then execute it as a non-root user.
