Currently it seems that exctags processes only the grammar definition of a .y files (the middle section). However, there might be C functions in the third section of the file and these are not tagged. The third section is separated by the 2 percentage marks (%%) so it should be easy to detect this.
Universal-ctags(http://ctags.io), a project forked from Exuberant-ctags has ability to run C parser in the areas of yacc file.
