Comment (by ballapete):

 In the `pre-processed` output I find

 {{{
 int setenv(const char *, const char *, int) ;
 ...
 void unsetenv(const char *);
 # 260 "/usr/include/stdlib.h" 3 4
 }}}

 coming from

 {{{
 int      setenv(const char *, const char *, int) __DARWIN_ALIAS(setenv);
 ...
 #if __DARWIN_UNIX03
 int      unsetenv(const char *) __DARWIN_ALIAS(unsetenv);
 #else /* !__DARWIN_UNIX03 */
 void     unsetenv(const char *);
 #endif /* __DARWIN_UNIX03 */
 }}}

 in `/usr/include/stdlib.h`. And
 `cmake-3.10.0/Utilities/cmlibuv/src/unix/core.c` has

 {{{
  1280   int uv_os_setenv(const char* name, const char* value) {
  1281     if (name == NULL || value == NULL)
  1282       return -EINVAL;
  1283
  1284     if (setenv(name, value, 1) != 0)
  1285       return -errno;
  1286
  1287     return 0;
  1288   }
  1289
  1290
  1291   int uv_os_unsetenv(const char* name) {
  1292     if (unsetenv(name) != 0)
  1293       return -errno;
  1294
  1295     return 0;
  1296   }
 }}}
