Don't define __STRICT_ANSI__, we should build both with and without it.

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