The following information is from "Section 4: Sample Multiple-Thread C
Program" of the Microsoft C version 5.10 MTDYNA.DOC file.

4.3   Possible Problem Areas

Several possible problems may occur when creating, linking, or
executing a multiple-thread C program. Some of the more common ones
are listed below. The symptom is listed first, followed by the likely
cause:

1. LINK searches for xLIByz.LIB

   This is caused by omitting the /NOD option from the LINK command.
   If /NOD is omitted, LINK searches for the default library. The
   default library should NOT be used with multiple-thread programs.
   The /NOD option tells the computer not to search the default
   libraries. This problem may also be avoided by compiling with the
   /Zl option which suppresses default library search records in the
   object files.

2. You get the following execution error:

      SYS1943: A program caused a protection violation.

   This is caused by failing to specify the condition "SS is not equal
   to DS" in the CL command invocation. Specify the correct conditions
   with the /Alfw customized memory-model option. Recompile the
   program with /Alfw.
