Right. If you have both installed, you need to manage your path so that
they point to the "right" binaries for the job. That's not to say that
you have to work this way. Using the '-mno-cygwin' switch for Cygwin's
gcc/g++ is a nice easy way to build both with and without cygwin1.dll
if that's what you need. Using the '-mno-cygwin' flag is designed to
exclude Cygwin libs, DLLs, and include files in favor of their MinGW
counterparts. Just make sure you have your mingw-runtime package installed
if you plan to work this way. It's really no more complicated than that.
If this doesn't work well, it's either a local configuration issue or a bug.
