clogger 1.0.1 - portability fixes

Minor portability fixes noticed on some systems.

There is a minor license change, it is now explicitly LGPLv2.1
and LGPLv3 and later versions at the project leader's
discretion.  It is no longer LGPLv2.1+, so it doesn't give a
blank check to the FSF to change the license on us.
