 Replying to [comment:15 komzpa]:
 > going to long double is just a matter of adding "long" all over the
 function, and has almost no performance penalty. Worth trying that first?

 My reading suggests that compilers can choose how to implement long
 double, and some may choose to implement it as plain double (including
 clang and MSVC?).  So that would not make it useful for GEOS in general-
 although we can try it to see if it works in some cases.
