Just cloning pharo-vm repo on windows 7, got this:

error: unable to create file mc/VMMaker.oscog.package/GeniePlugin.class/instance
/primSameClassAbsoluteStrokeDistanceMyPoints.otherPoints.myVectors.otherVectors.
mySquaredLengths.otherSquaredLengths.myAngles.otherAngles.maxSizeAndReferenceFla
g.rowBase.rowInsertRemove.rowInsertRemoveCount..st (No such file or directory)

:(

i suspecting windows refuses to create a file because its name is too long?
