L.S.,

On alphaev6-unknown-linux-gnu, I get:

./xgcc -B/usr/snp/alphaev6-unknown-linux-gnu/bin/ -B./ -isystem
/usr/snp/alphaev6-unknown-linux-gnu/include -O2   -DIN_GCC    -W -Wall

-I../../egcs/gcc/config -I../../egcs/gcc/../include \
  -c ../../egcs/gcc/cp/tinfo.cc
cc1plus: warning: Ignoring command line option '-Wstrict-prototypes'

in stage 2 (i.e. the ./cc1plus compiler is the stage 3 compiler).
