17// NB: This file contains macros for checking binary compatibility of libraries
18// in multilib builds, plugins and user components.
19// The WX_BUILD_OPTIONS_SIGNATURE macro expands into string that should
20// uniquely identify binary compatible builds: i.e. if two builds of the
21// library are binary compatible, their signature string should be the
22// same; if two builds are binary incompatible, their signatures should
23// be different.
24//
25// Therefore, wxUSE_XXX flags that affect binary compatibility (vtables,
26// function signatures) should be accounted for here. So should compilers
27// and compiler versions (but note that binary compatible compiler versions
28// such as gcc-2.95.2 and gcc-2.95.3 should have same signature!).
