1) Yes! finally! A native win64 version of my C module. Currently win32 
- msdblib, linux32/linux64/win64 - freetds! You can always count on 
"good old open source", to come to the rescue from windows. This saves 
me a boatload of problems. Thanks freetds!

2) Yes I should have been more clear. The --prefix and --includedir were 
intentional, as I wanted to place the build output in a place with all 
the other related cross compiler stuff.

3) The magic touch was the PATH, not CC. I have never understood until 
now that the --host thing is just looking for tool prefixes. Thanks man!

4) --enable-shared seems to not yield a dll. Although this is not a 
technical problem, is this still in the spirit of LGPL?

5) For google search posterity sake, kids try something like:

PATH=$PATH:/path/to/your/toolchain/bin ./configure --host=toolchain_prefix
(where "toolchain_prefix" is the part of the filenames (not including 
the '-') like toolchain-prefix-gcc and toolchanin-prefix-g++)
PATH=$PATH:/path/to/your/toolchain/bin make

Also once back over in windows, set your FREETDS environment variable to 
the directory containing freetds.conf.
