Subject: Presence of pthread_mutex_t::__m_kind or pthread_mutex_t::__data.__kind is now detect... 
X-Git-Tag: svn/VALGRIND_3_4_0~753
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=94c9786ea11995986061e9d09b3547a68a27e97a;p=thirdparty%2Fvalgrind.git

Presence of pthread_mutex_t::__m_kind or pthread_mutex_t::__data.__kind is now detected by configure. DRD now halts if configure could not find either of these two data members.
