# Third digit in PV should be incremented after a minor release
# happens from this branch on gcc e.g. currently its 4.7.1
# when 4.7.2 is releases and we bump SRCREV beyond the release
# on branch then PV should be incremented to 4.7.2+svnr${SRCPV}
# to reflect that change

# using 4.7.1.0 for upgrade path when we move past 4.7.2 release
# then we should drop the last 0 as well.

# BINV should be incremented after updating to a revision
# after a minor gcc release (e.g. 4.7.1 or 4.7.2) has been made
# the value will be minor-release+1 e.g. if current minor release was
# 4.7.1 then the value below will have 2 which will mean 4.7.2
# which will be next minor release and so on.
