The QuickC online help system documents support for the following four
pragmas:

   check_stack, check_pointer, message, and pack

Six pragmas are actually supported, but using any of the others (which
are also supported by the C 6.00 compiler) with QuickC will have no
effect, even though warnings are generated for only four of them.

Below is a list of pragmas supported by the C compiler version 6.00
and the behavior exhibited by QuickC versions 2.00 and 2.50 when they
are encountered in a source file. Those that are not supported and
that actually issue a warning will generate the following warning
message:

   C4118: pragma not supported

   A pragma that the compiler does not support was used. The pragma
   was ignored.
