Description

See below for output of running configure. I saw the unusual command not found errors. I looked at the lines indicated and discovered some odd Unicode characters. I replaced the octal characters \357\277\274 (in hex: \xEF\xBF\xBC), with spaces in my local copy of configure, and ran it again. This seemed to resolve the problem.

From my limited exploration of where these characters came from, it looks like they were introduced in commit 119eb49 into lines 31599 and 31600 (as they were back then).
