What?! header files are for prototypes and inline functions. Any other use 
(like a way to emulate a library including code) is a very bad practise and 
will produce hard problems soon or later in your project.

1) Move the code to a .cc file.
2) If you still having problems and have the time patch the compiler to allow 
the generation of STABs debug info.
