%bcond_without annobin_plugin

# Allow the building of annobin without using annobin itself.

# 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.

#

# The default is to use annobin.  cf BZ 1630550.

# [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

#   gcc (GCC) 4.6.1 20110908 (Red Hat 4.6.1-9)

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

#   This is free software; see the source for copying conditions.  There is NO
