[net.unix-wizards] whoami useless in setuid programs

Christopher A Kent <cak@PURDUE.ARPA> (11/20/84)

Description:
	whoami returns the real user id, not the effective user id.
Repeat-By:
	create a setuid shell script and run whoami inside it.
Fix:
	Simple -- change the getuid() call in whoami.c to geteuid().
	Must have been overlooked in the 4.2 conversion.
