From 4a7895d8c1f8b08ebd0e3bcfd975783fcc8bd057 Mon Sep 17 00:00:00 2001 From: Ken Raeburn Date: Wed, 2 Jun 2004 23:47:36 +0000 Subject: [PATCH] * k5-thread.h: Error out at compile time if thread support is enabled but the thread system isn't pthreads. (This is after the code disabling thread support for non-pthreads systems, so it's a placeholder for now that should never get invoked.) git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@16393 dc483132-0cff-0310-8789-dd5450dbe970 --- src/include/ChangeLog | 5 +++++ src/include/k5-thread.h | 20 ++++++++++++++++++++ 2 files changed, 25 insertions(+) diff --git a/src/include/ChangeLog b/src/include/ChangeLog index 87707074e..9fe30891b 100644 --- a/src/include/ChangeLog +++ b/src/include/ChangeLog @@ -1,5 +1,10 @@ 2004-06-02 Ken Raeburn + * k5-thread.h: Error out at compile time if thread support is + enabled but the thread system isn't pthreads.
