[ REQ 5402]: src/lib/mg/ps and SVR4

["Paul Burchard" <burchard at geom>]

The following gv source files use the random() function, which is  
not supported on strict SVR4 platforms, such as Solaris 2.4:

	src/lib/mg/ps/rand.c
	src/lib/mg/ps/handline.c

Here's what I added to the top of both files to fix this:

#if (defined(__svr4__) || defined(SVR4) || defined(SYSTYPE_SVR4) ||  
defined(_SVR4_SOURCE))
#include <stdlib.h>
#define srandom(x)	(srand48((long)(x)))
#define random()	(lrand48())
#endif

For handline.c, you'll also want to remove the declaration of  
random() from the function init_noise3(), or if you prefer, to move  
it into the #else clause of the above #if.
