No, you still need single/multi-threaded builds, but with out headers, I 
then need to add in 4-byte alignment builds, 8-byte alignment builds, 
different builds for different calling conventions etc.  It doesn't get 
easy, especially for existing projects.  We either end up making a 
custom build of the boost libs for each project?  That would become a 
maintanence nightmare.

How would you feel if you had to re-build your compiler's RTL just so 
you could change some project options?

Then we put options in to ignore the pre-post config headers so users 
can user there own settings if they wish, but it appears to me that most 
people don't care what options are set, they would just rather have it 
work, and currently, its very easy to break things as soon as you use a 
compiled lib.
