Should the patch be relative to commit 6d6fc91c472fd84bd71a1b012fa9ab77bd94efea (before the version requirement bump) or should it include reverting commit 4e3744a15c4d8bdb46c11ead2fb56c5f591b714b (the version requirement bump)?

Might as well do it all at once, thanks.

This second patch is the change I previously suggested. As noted in the patch, please use my address for public attribution. (I would prefer to minimize any indirect advertising of GMail.)

I have found no better ChangeLog entry than the commit message:

* lib/Automake/ Gracefully degrade if Time::HiRes is not available.
