The warning below is from Section D.1.3 (Page 340) of the "Microsoft
QuickC Programmer's Guide" and Section E.3.3 (Page 269) of the
"Microsoft C Optimizing Compiler User's Guide" for Version 5.00 and

This message indicates potential problems but does not hinder
compilation and linking. The number in parentheses at the end of a
warning-message description gives the minimum warning level that must
be set for the message to appear.

The following is the warning:

C4086       expected [1|2|4]

            An invalid argument was given for a "pack" pragma, as
            in the following example:

            #pragma pack (yes)

The "pack" pragma is used when you want to specify packing other than
the packing specified on the command line for particular structures.
The /Zp option and the "pack" pragma control how structure data are
packed into memory.

For detailed information on the /Zp option and the "pack" pragma, see
Page 210 of the QuickC programmer's guide and Page 100 of the C user's
guide.
