IF YOUR ISSUE IS RELATED TO SECURITY
please submit it to the security mailing-list security at riot-os.org.
If your issue is a question related to the usage of RIOT, please submit it to
the user mailing-list users at riot-os.org or to the developer mailing-list
devel at riot-os.org.
Example: Cannot build gnrc_networking application for samr21-xpro board.
Since #10989 was merged, most RIOT applications don't compile on MAC anymore, as there is a type `thread_state_t` also defined in [Apples thread handler headers](https://opensource.apple.com/source/xnu/xnu-792/osfmk/mach/thread_status.h.auto.html). As a fix I propose to rename that type to something that collides less with that particular type.
#### Steps to reproduce the issue
Build e.g. `examples/gnrc_networking` for `native` on a MAC-OSX-based machine.
Try to describe as precisely as possible here the steps required to reproduce
the issue. Here you can also describe your hardware configuration, the network
#### Expected results
The application should compile.
Example: The gnrc_networking application builds on samr21-xpro.
#### Actual results
The application can't compile with the following error:
/Users/mlenders/RIOT/core/include/sched.h:117:3: error: typedef redefinition with different types ('enum thread_state_t' vs 'natural_t *' (aka 'unsigned int *'))
/usr/include/mach/thread_status.h:83:20: note: previous definition is here
typedef natural_t *thread_state_t; /* Variable-length array */
1 error generated.
Please paste or specifically describe the actual output.
Operating system: Mac OSX, Linux, Vagrant VM
Build environment: GCC, CLang versions (you can run the following command from
the RIOT base directory: ./dist/tools/ci/print_toolchain_versions.sh).
