On Linux systems, this function is provided by the BSD compatibility
libraries.  Use

#include <bsd/stdlib.h>

and link against libbsd.

Unfortunately the Linux package does not provide manual pages for
getprogname/setprogname -- see
http://netbsd.gw.com/cgi-bin/man-cgi?getprogname++NetBSD-current
instead.
