handling the same names of unnamed enum member and define

[Dushistov]

Input C/C++ Header

This is reduced test case. I created it based on headers of glibc 2.26.
You can see in comments from which standard headers I got C code.

//netinet/in.h
enum
  {
IPPORT_RESERVED = 1024,
};
//netdb.h
# define IPPORT_RESERVED        1024

Bindgen Invocation

$ ~/bin/bindgen.sh --no-layout-tests --no-rustfmt-bindings test.h  | ~/bin/rustfmt-nightly.sh

Actual Results

/* automatically generated by rust-bindgen */

pub const IPPORT_RESERVED: ::std::os::raw::c_uint = 1024;
pub const IPPORT_RESERVED: _bindgen_ty_1 = 1024;
pub type _bindgen_ty_1 = u32;

as result compile time error from rustc:

the name `IPPORT_RESERVED` is defined multiple times

Expected Results

I'm creating bindging for 3rdparty library, and it's headers indirectly include both headers (netdb.h and netinet/in.h).
It would be nice to add some kind of mechanizm to prevent such kind of errors
without need to edit glibc headers or 3rdparty library's headers.

Thanks for filing an issue!

Closing as a dupe of #687.

What is the solution? Also getting > IPPORT_RESERVED must be defined only once in the value namespace of this module
