To suppress PCH file processing, use the
no_pch directive in the primary source file. You do not
have to place this directive at the beginning of the file for it
to take effect. For example, no PCH file is created if you compile
the following source code with
#include "xxx.h" #pragma no_pch #include "zzz.h"
If you want to selectively enable PCH processing, for example,
xxx.h to PCH file processing, but not
#pragma no_pch with
hdrstop, as follows:
#include "xxx.h" #pragma hdrstop #include "zzz.h"
