The problem is that the UDUNITS package was designed for a POSIX environment 
and MinGW isn't quite that environment.

I see these options: 1) give up; 2) migrate your processing to a POSIX 
computer; 3) install a POSIX virtual machine (e.g., VMplayer from VMware along 
with Ubuntu -- they're both free); and 4) modify the source-code so that it 
works under MinGW.

The first step in the last option would be to define _POSIX_MAX_INPUT to be 255.
