Subject: Back out the shared mutex code since it only works when the mutex is in shared
X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=db1b99d8dd0b6280c60729048b9699bcd190f324;p=simgear.git

Back out the shared mutex code since it only works when the mutex is in shared
memory[1], something we don't support anyhow.
This also fixes a FreeBSD compile problem.
