Could you please post the exact error message, along with the code lines
it belongs to? I think you've actually got two problems.

One was already explained by various list readers, you'd better use
appropriate header guards.

But "redefinition" and a new declaration are basically two different
things, so I think there's also the error around that your header file
possibly contains actual definitions of variable (instead of only
declarations for those...).
