shortly after I reported FreeBSD, I tried NetBSD and got the same error.
Now, after your patch, NetBSD is fixed, but FreeBSD still fails to compile.

NetBSD just gives a warning about the qualifier:


NSThread.m: In function '-[NSThread _setName:]':
NSThread.m:810:7: warning: passing argument 3 of 'pthread_setname_np' 
discards 'const' qualifier from pointer target type [enabled by default]
       result = PTHREAD_SETNAME(pthread_self(),
       ^
In file included from NSThread.m:46:0:
/usr/include/pthread.h:133:5: note: expected 'void *' but argument is of 
type 'const char *'
 int pthread_setname_np(pthread_t, const char *, void *);
     ^

While FreeBSD gives this error:
 Compiling file NSTask.m ...
 Compiling file NSThread.m ...
NSThread.m:810:16: error: too few arguments to function call, expected 
2, have 1
      result = PTHREAD_SETNAME(pthread_self(),

The relevant configure test is I suppose:

configure:13718: checking for pthread_set_name_np
configure:13774: clang -o conftest -g -O2  -I/Local/Library/Headers 
-I/Local/Lib
