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