|
// by default Loki is compiled without thread support, so we must disable the dependency on thread classes (StrongPtr) to avaoid linker errors when compiling with the default build process. Should we change the default threading of Loki?
|
|
//
|
|
// Revision 1.3 2006/10/14 00:06:15 rich_sposato
|
|
// Fixed a couple of bugs. Added lines to send test info to output. Added
|
|
// use of ScopeGuard. Removed superfluous code.
|
|
//
|
|
// Revision 1.2 2006/06/08 19:15:27 lfittl
|
|
// - Simplify some threading code by not saving the return status
|
|
// (also fixes 2 gcc warnings)
|
|
//
|
|
// Revision 1.1 2006/04/28 00:34:21 rich_sposato
|

// Added test for thread-safe StrongPtr policy.
