I'm porting PROJ4.3.3 (the cleanest version of proj I could find), and it's a little ugly.
One thing leading to another, I am currently centralizing constants, and found that enums can hold doubles (which is quite nice), but I have no way of defining NaN or Inf as a constant, is there such a way? Or is there a way to evaluate constant functions at compile time (eep)? Or I could just use #define (much safer than the above). enjoy, tristan -- All original matter is hereby placed immediately under the public domain.
