# Decide which version of the annobin plugin for gcc should be used.
# There are two possible versions, one created by the annobin package and one
# created by the gcc package. The logic selects the gcc version unless both
# have been built by the same version of the compiler. In that case the
# annobin version is selected instead.
#
# The point of all this is that the annobin plugin is very sensitive to
# mismatches with the version of gcc that built it. If the plugin is built
# by version A of gcc, but then run on version B of gcc, it is possible for
# the plugin to misbehave, which then causes problems if gating tests examine
# the plugin's output. (This has happened more than once in RHEL...).
#
# So the plugin is built both by gcc and by the annobin package. This means
# that whenever gcc is updated a fresh plugin is built, and the logic below
# will select that version. But in order to allow annobin development to
# proceed independtently of gcc, the annobin package can also update its
# version of the plugin, and the logic will select this new version.
# This is where the annobin package stores the information on the version
# of gcc that built the annobin plugin.
