0.8.20.31:

0.8.20.31:
	Has it been a month already? Bump +FASL-FILE-VERSION+. Reasons:
        * "0.8.20.6: Make FILE-STREAM and STRING-STREAM potential mixins
           in CLOS"
        * "0.8.20.21: Add immediate single-floats on x86-64."
        * Probably others...

        Restore a modified version of the "slightly odd-looking stuff"
        that was removed in 0.8.20.30. It's there because the arch name
        is "x86-64" but the config file suffix is "x86_64-linux".
