Exclude.h

Program A-6 defines numerous variables that will exclude definitions not required by the programs in the book. Rector and Newcomer (1997) discuss this in detail.

Program A-6. Exclude.h Include File

/* Exclude.h -- Define variables to exclude selected header files.

For a complete explanation, see Rector & Newcomer, Win32

Programming, pp 25ff. */
#define WIN32_LEAN_AND_MEAN

/* This has the largest impact, halving the precompiled

header (pch) file size. */
/* These definitions also reduce the pch and improve compiling

time. All the programs in the book will still compile with

these definitions. You can also eliminate security with

#define NOSECURITY. */
