	the efficiency / speed of compilation advantage when using precompiled
header.

	from watcom help files on precompiled headers:
	"Using precompiled headers reduces compilation time when:
...
	Your program comprises multiple modules, all of which use the same
first #include file and the same compilation options. In this case, the
first #include file along with all the files that it includes can be
precompiled into one precompiled header.
"

	With best regards - Leon.
