This is not completely true, but the changes in the versions 9 and 10 of g++ ABI don't (seem to?) affect wxWidgets, so allow using later versions of the compiler for building the code using the libraries created using earlier ones.

// 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!).
