Comment (by thomie):

 Some projects have changed their code:
 {{{
 #if _WIN64
 #define STRDUP _strdup
 #else
 #define STRDUP strdup
 #endif
 }}}

 * https://github.com/snoyberg/yaml/pull/45

 * https://github.com/bsl/bindings-
 GLFW/commit/86271bcff4897c1c563af0058111705111d1ba7e

 We should probably not add any special cases to the linker (it's
 complicated enough already!) to effectively un-deprecate those functions.
 It is still rather unfortunate that those ifdefs are unnecessary though.

 @snoyberg might have an opinion, since he mentioned in
 https://github.com/snoyberg/yaml/issues/44#issuecomment-46459264:

     "There's no good reason why C code being compiled by GHC should need
 to be modified to avoid using strdup, that's certainly a bug in the
 toolchain, not the code."
