dwt-win build problem

[Bill Baxter]

FYI, I was trying to build dwt-win with latest SVN Tango and latest hg 
dwt-win sources.

The README.txt in dwt-win says you should turn off DSSS's oneatatime 
setting to speed up compiles.  But after doing that I got link errors 
using DMD 1.025 / DSSS 0.75:

--------------------

Turning oneatatime back on fixed the problem.  So I think maybe the 
README shouldn't be recommending changing this setting.  Or maybe it can 
offer it as a hint to speed up building the lib, but then say it should 
be set back to "oneatatime: yes" after the lib is built.
