As an experiment try setting /home/richard 755. You also might add calls to:
uid_t getuid(void); uid_t geteuid(void); gid_t getgid(void); gid_t getegid(void); just before the call to getcwd. The following should *not* be relevant, but circa 1998, Sun made a change such that getcwd would set errno even though the call succeeded. This broke code I'd written 6 years earlier that ran on AIX, Irix, Clix, Ultrix, HP-UX and Solaris and required no maintenance during that time. The friend who fixed it related this over lunch one day. His solution was to modify the failure test to check for a null pointer being returned instead of the traditional clearing and testing of errno that I used. Have Fun!
