# # Do not build the annobin plugin with annotation enabled.
# # This is because if we are bootstrapping a new build environment we can have
# # a new version of gcc installed, but without a new of annobin installed.
# # (i.e. we are building the new version of annobin to go with the new version
# # of gcc).  If the *old* annobin plugin is used whilst building this new
# # version, the old plugin will complain that version of gcc for which it
# # was built is different from the version of gcc that is now being used, and
# # then it will abort.
#
# Suppress this for BZ 1630550.
# The problem should now only arise when rebasing to a new major version
# of gcc, in which case the undefine below can be temporarily reinstated.

# [Stolen from gcc-python-plugin]
# GCC will only load plugins that were built against exactly that build of GCC
# We thus need to embed the exact GCC version as a requirement within the
# metadata.
#
# Define "gcc_vr", a variable to hold the VERSION-RELEASE string for the gcc
# we are being built against.
#
# Unfortunately, we can't simply run:
#   rpm -q --qf="%%{version}-%%{release}"
# to determine this, as there's no guarantee of a sane rpm database within
# the chroots created by our build system
#
# So we instead query the version from gcc's output.
#
# gcc.spec has:
#   Version: %%{gcc_version}
#   Release: %%{gcc_release}%%{?dist}
#   ...snip...
#   echo 'Red Hat %%{version}-%%{gcc_release}' > gcc/DEV-PHASE
#
# So, given this output:
#
#   $ gcc --version

#   Copyright (C) 2011 Free Software Foundation, Inc.
