on hpux the compilation fails with the following error message:

/usr/ccs/bin/ld: Unsatisfied symbols:
   getpt (first referenced in util.o) (code)
   asprintf (first referenced in util.o) (code)

it tried to add the failing functions(), to gnome-system-monitor-
2.4.0/src/util.c

#if defined(__hpux)

                errno = ENOENT;
                return -1;
        }
        return master;

finaly system-monitor compiles, but with warnings:

util.c: In function `getpt':
util.c:72: warning: passing arg 1 of `open' from incompatible pointer type
util.c:72: warning: passing arg 2 of `open' makes integer from pointer without 
a cast

could someone check this hack ?
