 Summary of the bug:
 How to reproduce:
 {{{
 # link /bin/sh to zsh
 % ./configure
 ./configure:6493: parse error near `}'
 }}}

 There is a semicolon missing before the closing bracket in the openal
 check. Other shells seem to gloss over that slight mistake but zsh, when
 run as sh, seems to be very strict.

 A look into the manual of dash, which claims to be the most POSIX
 compliant shell, shows that grouped command lists must always be finished
 with a semicolon. I believe this is also what POSIX says but have not
 found the text to back up this claim, yet.
