dnl For projects using a fourth or nano number in your versioning to indicate

dnl development or prerelease snapshots, this macro allows the build to be

dnl - parses AC_PACKAGE_VERSION, set by AC_INIT, and extracts the nano number
44
dnl - sets the variable PACKAGE_VERSION_NANO
45
dnl - sets the variable PACKAGE_VERSION_RELEASE, which can be used
46
dnl for rpm release fields
