You can selectively include and exclude header files for PCH
file processing, even if you are using automatic PCH file processing.
Do this by inserting a manual header stop point using the
hdrstop directive in the primary source file. Insert it
before the first token that does not belong to a preprocessing directive.
This enables you to specify where the set of header files that is
subject to precompilation ends. For example,
#include "xxx.h" #include "yyy.h" #pragma hdrstop #include "zzz.h"
In this example, the PCH file includes the processing state
zzz.h. This is useful if you decide
that the information following the
#pragma hdrstop does
not justify the creation of another PCH file.
