[Coin-discuss] cygwin build

Tue Aug 15 14:53:50 EDT 2006

I'm trying to change the default behavior later today - at least for the 
development branches.

In the meantime, you can always overwrite the default compilation flags 
picked by configure by setting them in the command line, e.g.,

./configure CXXFLAGS='-O3' CFLAGS='-O3'

More information about the general configuration can be found at

https://projects.coin-or.org/BuildTools/wiki/user-configure

Hope this helps

Andreas
