A neat trick you can try in order to avoid multiple declarations if that
is 
your problem is........

-- file.h --

#ifndef file_h
#define file_h

<CODE GOES HERE>

#endif

-- eof --

This way, a source file will never be compiled more than once.
When it is compiled the compiler will define file_h, and then next
time the file will be skipped because file_h is defined.
