# This version does not work as the configure script expects the installed
# cross-compiler to be able to link binaries ... except we haven't provided
# any of the crt objects yet so it is impossible to link binaries.
# Older mingw-runtime packages hacked around the issue, but this version seems
# to have dropped said hack thus breaking the package.
