I think you just have been lucky. I've had this in my .vimrc for a few days shy
of four years now, to allow me to find the definition before the declaration:
" -R : recursive
" --extra=+f : include file name as a tag
" --fields=+S : include signature (e.g. parameter list)
" K : include kind of tag as full name
" -k : not kind of tag as single letter
" --totals : print on standard output total number of tags, etc.
" -B : reverse search order for definitions
" --c-kinds=p : only generate function prototype in C code, normal search
order
" -a : append to existing file
let ctags_command= ctags_exec.' -R --langmap=c:+.pro
--extra=+f --fields=+SK-k --totals -B .'
let ctags_command=ctags_command.' & '.ctags_exec.' -R --langmap=c:+.pro
--extra=+f --fields=+SK-k --totals --c-kinds=p -a .'
It works because the definitions use a backwards search so that it searches up
from the bottom of the file instead of down from the top, finding the LAST
match for the pattern in a given file.
