# # 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
