This is probably a Macintosh/Windows/UNIX line ending issue.  I use the  
Metrowerks IDE
on the Mac and it has a predilection for choosing Macintosh rather than  
UNIX style line
endings.  I've gone through and manually changed these for all the  
files.  Hopefully the
problem will go away.

I've just finished boostifying most of the library; I decided to use  
boost::units to mirror
the existing namespace structure, but naturally I'm not wedded to it.   
I'm too cheap to
buy Stuffit for my machine, so I'll need to figure out how to get gzip  
to retain directory
info first... For now you'll find two archives in the Yahoo files  
section, one for headers
and one for test files.

Also, as Phil Richards mentioned, there are two loosely related  
sub-components to the library :
the dimensional analysis portion and the units portion, the latter  
depending on the former but not
vice-versa.  Perhaps it makes sense to decouple them as separate  
libraries, since the dimensional
analysis engine is unit system and angle agnostic (demonstrated in  
test_dimensional_analysis.cpp
and test_merged.cpp).
