Adjust to the moving target called the C++ standard. Apparently nowadays it's not allowed to define an explicit copy constructor but not an assignment operator. Consequently, defining the explicit copy constructor in terms of the implicit/automatic assignment operator for general convenience no longer works. Add assignment operators. Caution: not tested with the IBM compiler, but there's no particular reason it shouldn't work.

#!/bin/sh
# cppfilt - wrap the IBM compiler's cppfilt
# (all this does is run wine)

WINEPATH='I:\\ibmcppw\\bin'
export WINEPATH

exec wine 'I:\\ibmcppw\\bin\cppfilt.exe' "$@"
