// NB: This file contains macros for checking binary compatibility of libraries
// in multilib builds, 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!).
