Description of problem:
I just tried to compile package transfig-3.2.4-5 from Fedora.

The compiler said

1.

genmp.c:649: warning: operation on `j' may be undefined
genmp.c:653: warning: operation on `j' may be undefined

The source code is

	for ( ; p->next != NULL; ) {  /* 3 or more points */
		fprintf(tfp,"    p%d..controls c%d and c%
d..\n",i++,j++,j++);
		p = p->next;
	}
	if (s->type == 1)     /* closed spline */
		fprintf(tfp,"    p%d..controls c%d and c%
d..cycle;\n",i++,j++,j++);

This source code is undefined because j is incremented twice between
sequence points. Better source code is

	for ( ; p->next != NULL; ) {  /* 3 or more points */
		fprintf(tfp,"    p%d..controls c%d and c%d..\n",i++, 
j, j + 1);
		j += 2;
		p = p->next;
	}
	if (s->type == 1)     /* closed spline */
	{
		fprintf(tfp,"    p%d..controls c%d and c%
d..cycle;\n",i++, 
					j, j + 1);
		j += 2;
	}
