20050112: problem building udunits on freebsd 4.7-RELEASE

Neil,

I was able to build the latest version of the UDUNITS package on
coriolis.met.tamu.edu by setting environment variables CC to "cc" and
CPPFLAGS to "-Df2cFortran" before executing the configure(1) script.

The problem you encountered reveals a problem with the installation
of the UDUNITS package that I will fix in the next release.  Basically,
the configure(1) script insists on using the "-O2" option even though
the GNU C compiler doesn't accept that option with invoked as c89(1).

Thanks for sending this in.

Regards,
Steve Emmerson
