I dunno. You're the programmer around here so you go figure it out :-)
Common sense tells me that if a program includes math.h then it should link
against -lm. But there may be reasons why that is not true.

discovered it fails when compiling with no optimisation at all (-O0) so
maybe the ceil rounding function gets optimized away by the compiler or
