...ntly yes. not generally, though. [...] > What's *intended* re: openssh? Support for LD=ld or only =gcc, or undef'd ? Well the intent is you should be able to set CC and LD to whatever you want as long as they work. In this case, the OSSH_CHECK_LDFLAG_LINK test invokes autoconf's AC_LINK_IFELSE with uses CC not LD. I'm not sure what to do about it yet though. -- Darren Tucker (dtucker at dtucker.net) GPG key 11EAA6FA / A86E 3E07 5B19 5880 E860 37F4 9357 ECEF 11EA A6FA (new) Good judgement comes with experience.

http://dovecot.org/test/ This release is built with autoconf 2.59 and libtool 1.9. We'll see how it works out :) The required changes were done by Matthias Andree. - The last fix for connection hanging made IDLE use 100% CPU - We don't use Maildir/.INBOX/ directory anymore, indexes are stored in Maildir-root - Don't crash with FETCH BODY[n.MIME] - Changed %p (protocol)

Patch 1 adds a check for the compilers visibility macro to configure.ac. Patch 2 avoids redefined symbol errors in clang of the tls entry points. Based on a suggestion from Rafael Ávila de Espíndola <rafael.espindola at gmail.com> in http://llvm.org/bugs/show_bug.cgi?id=19778. Tested with gcc 4.9 and clang 3.6(rc) Marc Dietrich (2): configure: add visibility macro detection to configure

Hi Erik, similar to what I did for libsndfile, this is to simplify the handling of adding -D_FORTIFY_SOURCE=2. Regards David

I don't see a way to get AC_LINK_IFELSE to use $LD rather than $CC, but I think we can prevent this problem by detecting the unsupported option earlier. Please try this diff. It should also prevent the warnings...
