You don't need this

pygccxml.declarations.declarations_files
But you also don't need this functionality

My idea was next:

class mbcache_t( pygccxml.parser.base_cache_t ):
    def __init__( self, *args ):
         pygccxml.parser.base_cache_t.__init__( self )
         test whether there is a need to load from cache on disk
         self.decls_cache = pygccxml.parser.file_cache_t( file_name )

   def update( self, .... ):
         self.decls_cache.update( self,  .... )

   def flush( self, ... )
        self.decls_cache.flush()
        write to disk files passed to module_builder_t

Thus, mbcache_t only needs to warry about files list that was passed to
module_builder_t

I think this is pretty simple idea, that will take few hours to implement.

What do you think?
