# To get the code building on FreeBSD and Arch Linux we seem to need the following
# warning suppression to work around some issues in Boost headers.
#
# See the following reports:
# https://github.com/ethereum/webthree-umbrella/issues/384
# https://github.com/ethereum/webthree-helpers/pull/170
#
# The issue manifest as warnings-as-errors like the following:
#
# /usr/local/include/boost/multiprecision/cpp_int.hpp:181:4: error:
# right operand of shift expression '(1u << 63u)' is >= than the precision of the left operand
#
# -fpermissive is a pretty nasty way to address this. It is described as follows:
#
# Downgrade some diagnostics about nonconformant code from errors to warnings.
# Thus, using -fpermissive will allow some nonconforming code to compile.
#
# NB: Have to use this form for the setting, so that it only applies to C++ builds.
# Applying -fpermissive to a C command-line (ie. secp256k1) gives a build error.
