Currently libpqxx 2.5.5 tries to build with -Werror enabled, unfortunately this makes the test for strerror_r fail because it's called with a NULL parameter, that throws an a warning that get escalated to error by -Werror. The attached patch disables -Werror so that the build is done without it and users aren't bothered by new warnings of recent gcc versions. The patch also changes another thing: it disables -fvisibility-inlines-hidden support, so we're safe that it doesn't build PIC-incompatible libraries (see bug #78720). After applying the patch, an eautoreconf call is needed (from autotools eclass). If you get me the okay, I can commit this myself. Thanks, Diego

Version 2.5.5 was compiled fine with gcc-4.1.1 for me.
(In reply to comment #1) Same error here. Luckily libpqxx-2.5.5 works fine.

Stupid bugzilla... Should block the other bug, not dupe.
Fixed for version 2.6.8.
