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

Currently the build systems sets ARCH based on the result of 'uname -m'. On a mixed 32/64 system (one with a 64-bit kernel and a 32-bit userspace) this will result in "x86_64" which is wrong. We'd like the ARCH variable to represent the userspace we're compiling in/for, not what the kernel happens to be. Does anyone know of a clean way to detect this sort of system

...e ARCH variable to represent the userspace we're compiling > in/for, not what the kernel happens to be. > > Does anyone know of a clean way to detect this sort of system > configuration? Cleanest way is probably to explicitly test if __x86_64__ is defined, ie AC_COMPILE_IFELSE([AC_LANG_PROGRAM( [[#ifndef __x86_64__ error: Not x86-64 even if uname says so! #endif ]])], [ARCH=x86_64], [ARCH=i386]) Or in the alternative you can always key off sizeof(void *) == 8. Cheers, Nathan

Hi everyone Following are a number of build-system cleanup patches. Some of them are prep-work for a possible upcoming automake/gnulib introduction. Best regards, Tiziano
