[Coin-discuss] cygwin build

./configure CXXFLAGS='-O3'

I presume this overwrites the rest of the CXXFLAGS with only -O3. What if I just want to remove -mno-cygwin and keep the rest? I don't know what the rest of the default CXXFLAGS are. I could just take the full list of flags and remove what I need - but, I don't know what they are or where to find them.
