#ifndef _WX_BUILD_H_
#include "wx/version.h"
+// NB: This file contains macros for checking binary compatibility of libraries
+// in multilib buildm, plugins and user components.
+// The WX_BUILD_OPTIONS_SIGNATURE macro expands into string that should
+// uniquely identify binary compatible builds: i.e. if two builds of the
+// library are binary compatible, their signature string should be the
+// same; if two builds are binary incompatible, their signatures should
+// be different.
+//
+// Therefore, wxUSE_XXX flags that affect binary compatibility (vtables,
+// function signatures) should be accounted for here. So should compilers
+// and compiler versions (but note that binary compatible compiler versions
+// such as gcc-2.95.2 and gcc-2.95.3 should have same signature!).
