 ANSI and K&R compilers differ in how they handle arument promotions.

 In fact, half or so of the gnuplot sources already have ANSI function
 definitions.

 At this point, we should switch to ANSI/ISO C throughout the source
 (maybe not just now for the new release). Not sure how many K&R compilers
 we need to support, but SunOS' cc worked quite well with the supplied
 ansi2knr, last time I checked (probably some time last year).
