Further to this issue, I've recompiled qmf in a pbuilder chroot with gcc-4.6 replacing gcc-4.7 and using compiler flags for -Wall -Wextra and -Werror in the src/libraries/qmfclient subdir and tests/tst_qmailthread/ sub directories without problems. There doesn't seem to be anything which gcc-4.6 can pick up as an error or warning in the qmf sources.
Reinstalling gcc-4.7 & g++-4.7 and rebuilding with the same flags (and the #include <unistd.h> patch) does not indicate any problems with the qmfclient library itself, g++-4.7 just fails to link the test binary. -- Neil Williams ============= http://www.linux.codehelp.co.uk/
