--- Comment #26 from Janez Zemva <janezz55 at gmail dot com> --- I am a c++ user, so I don't like using c header files if at all possible. I am pleased with how things are: I now compile/link a replacement libm and replace the sloppy djgpp header files, but I haven't tested this arrangement yet. Maybe it works.
