All of them matters to me and C11 in a public-header is no-go. We already have plenty of conditionals like this for C99 and C++ in public header files -- for example, __restrict, __BEGIN_DECLS, &c. Can't hurt to add #if (__STDC_VERSION__ - 0) > 201112L #define iconv ... #endif or whatever, if we want to do that. > > How about the Solaris 11 move?

[...] https://illumos.org/man/3C/iconv These calls with and without const should be ABI compatible. Can you explain how an application uses this, and how this helps? Does illumos use _POSIX_C_SOURCE vs _SOLARIS_SOURCE or something to select the declaration?
