Subject:	Unused variables

  In djgpp, how can I get a list of all variables and labels in a program
which are declared but not used? I was editing a program which someone wants
me to make it more efficient, and in the process many variables became
redundant, and I want to find them by some means quicker than having to search
for every one with my emacs's search-for-word.
