[patch] Reinitialize a pthread_once_t variable.

07271_all_charset_init_fix-5.1.44.patch (text/plain), 816 bytes, created by nietonfir on 2010-03-21 14:26:26 UTC

Workaround the pthread_once_t static initialization. Per the POSIX standard, reinitialization of a pthread_once is a gray area, but it is needed to support subsequent initializations of the client library (upstream bug 45058).
