Subject: New LinuxThreads detection.  Correctly detects FreeBSD's LinuxThreads port
X-Git-Tag: OPENLDAP_SLAPD_BACK_LDAP~234
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=bbb79645085753ece961bd5ab9a23f5232203562;p=openldap

New LinuxThreads detection.  Correctly detects FreeBSD's LinuxThreads port
(but not sure if it's usable yet).  Needs to be tested on various versions
of Linux native LinuxThreads.
