I'm filing this issue on behalf of a friend :)

What steps will reproduce the problem? Check the file configure.ac. All "enalbeval" should be changed to "enableval", and the file configure should thus be regenerated.

What is the expected output? What do you see instead? Variables should be able to be set when I pass --enable-...; but it is impossible to do so with this typo present.

What version of the product are you using? On what operating system? 1.5 and 1.6 on GNU/Linux
