Hi, The ECHO that is chosen by autoconf on darwin8 (printf %s\n) is buggy: fangism % printf %s\n foo foonfangism% printf '%s\n' foo foo Must be due to the version of the Bourne shell (2.05b). Failure is similar with sh-3.2. The 'correct' value of ECHO should be printf '%s\n' (note the extra single quote protection). I don't know yet whether that is forward-compatible with newer versions of Bourne shell. Don't recall which version of autoconf broke this, betweem 2.63 and latest.
The problem seems to be in the way that "printf '%s\n'" is assigned to as_echo.
