key_t in tests/hashtable_test.c may conflict with sys/types.h

[wRAR]

On kFreeBSD tests/hashtable_test.c fails to compile:

/«PKGBUILDDIR»/tests/hashtable_test.c:30:13: error: conflicting types for 'key_t'
 typedef int key_t;
             ^~~~~

It may be a coincidence that the conflict doesn't happen on Linux as <sys/types.h> there may define this type too.

Ugh, I'm sorry about that. There doesn't seem to be that typedef on linux.

That is just the unittest example and could use any name. I'll try to fix it as part of a big name audit.

There doesn't seem to be that typedef on linux.

Either the file doesn't get included or the conditions are false. There is that typedef in <sys/types.h> on my Linux.
