--------------------
01d,26dec06,kch  Removed references to the obsolete coreip virtual stack.
01c,04may05,dlk  Fix SPR #108879. Remove erroneous SEM_Q_FIFO flag
                 in semMCreate() and semOpen() calls.
01b,09mar05,dlk  Initialize the logging semaphore here rather than in
                 applUtilLib.c for better scalability (SPR #104991).
01a,12sep04,dlk  written.

DESCRIPTION

Configlette for applUtilLib (Application/Stack logging facility)
initialization.

Note, this file is included by both usrNetwork.c and bootConfig.c.
Make sure that any changes you make here do not break the command
line vxWorks and bootrom builds.
