Thanks for reporting that problem.  At the configure stage the
configure script defaults to using the ieee file for Freebsd for any
unknown BSD system (we don't have a corresponding file for Openbsd).

If you could find out what functions Openbsd uses to control rounding
mode and precision that could be added. 

To work around the problem edit the file config.h and comment out the
line,

#define HAVE_FREEBSD_IEEE_INTERFACE 1

and you should then be able to compile the rest of the library.
