AC_CHECK_USER
Check if the specified UNIX user exists, if yes set your environment variable to that username else unset your environment variable
Example:
AC_CHECK_USER(USER, [gleensalmon])
if test x$USER = xgleensalmon; then
bla..bla..bla..
else
bla..bla..bla..
fi
Besides checking existence, this macro also set these environment variables upon completion:
USER_HOME = home directory of user, written in /etc/passwd
