Comment (by rhaas):

 A grep for Werror in Cactus/configs/sim/scratch/build/PAPI/papi-5.1.0
 finds it in various places. *However* my own config-info turns on -Wshadow
 which then gives the error. So one solution is to filter out -Wshadow from
 Cactus' CFLAGS (or have users not use it together with PAPI). I attach a
 patch that removes the ones that I had set and the prevented a build.
 However even with no Cactus set flags it still failes to build
 {{{
