C complex number usage

What's the compiler version?  Assuming gcc or g++ try invoking
with only the -v option to learn the version.

Try adding the -E option and then looking at the resultant mess.
For example, if your compilation command is something like:

   g++    --your-specific-options-here -o yourProgram yourProgram.cpp

...then you might learn something by doing this:

   g++ -E --your-specific-options-here    yourProgram.cpp > /tmp/jnk.cpp

...which will dump the fully preprocessed glop into /tmp/jnk.cpp
where you can stare at it for further clues.

If you're not using the Gnu tools then your compiler probably has
similar capabilities that can be exploited in the same way.
