Hello,

I'm trying to build jsoncpp 1.8.4 with clang and libc++.

[5/10] Compiling C++ object 'jsoncpp@sha/src_lib_json_json_writer.cpp.o'.
FAILED: jsoncpp@sha/src_lib_json_json_writer.cpp.o

1.8.4

To my understanding, cstddef.h from libc++ does #include <version> and therefore includes the filename version in the project directory, which isn't a C++ header file, thus the error.

I don't know how we can fix that correctly though. Renaming that file?
