What is the right way to embed newlines in AC_MSG_FAIL or other AC_MSG_* macros? I have a wordy message I want to produce when bailing out of configure when a security feature was requested but can't be provided due to missing dependencies. This is for NTP, and previously the option would silently fall back to building an insecure configuration, but I want to bring it up to current best practices and croak loudly if a requested security-related option can't be fulfilled. I tried: AC_MSG_FAILURE( [--enable-openssl-random was used but no suitable SSL library was\ found. Remove --enable-openssl-random if you wish to build without\ a cryptographically secure RNG.\ WARNING: Use of ntp-keygen without a secure RNG may generate keys\ that are predictable.]) but it still came out as one long line broken randomly depending on terminal width, where I want to break on words before ~72 chars. -- Cheers, Dave Hart
