            Bug ID: 59193
           Summary: Unused postfix operator temporaries
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: minor
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: mtewoodbury at gmail dot com

The use of postfix operators without using the value in their inherent
temporary store is a mild abuse of languages that provide those operators. 
Compilers convert them to prefix operators as part of their optimization
process, but they waste space in automatic storage when the optimization is
insufficiently deep to detect them.

Reading the code in this project turns up hundreds of instances of this poor
practice.  Please convert these to the proper prefix operator form.

(More to the point, please accept patches that fix these problems without
abuse!  I have several sets that I will submit if there are no strong
objections.)
