--- Comment #1 from Dimitry Andric <dimitry at andric.com> ---
First, please note that FreeBSD 8.4 is end-of-life, and unsupported.  Same for
LLVM 3.5.0.

That said, https://svnweb.freebsd.org/base?view=revision&revision=297212, which
exposes a number of long long types and functions (among which strtoll), has
never been merged to stable/8.  So indeed, under C++ mode, there is no strtoll
in stdlib.h.

As a workaround, you can manually merge this into your stdlib.h:

--- head/include/stdlib.h       2016/03/23 18:21:26     297211
+++ head/include/stdlib.h       2016/03/23 19:17:12     297212

  */
-#if __ISO_C_VISIBLE >= 1999
+#if __ISO_C_VISIBLE >= 1999 || defined(__cplusplus)
 #ifdef __LONG_LONG_SUPPORTED
 /* LONGLONG */
 typedef struct {

Note that CMake is able to find strtoll, because it compiles a small C test
program, and for C strtoll is defined.

In any case, this will not be fixed anymore, either in FreeBSD or LLVM.
