   Log Message:
   gcc is too clueless on some platforms to tell that
   (number divisible by 2 * 1.5) is an int, and thus fails spectacularly
   at either link or compile time. replace exprs with their int values.


i wonder if the original intent could be better preserved by changing
this to "* 3 / 2"?
