'reference to static identifier "f" in extern inline function'.
This bug was observed with Sun C 5.12 SunOS_i386 2011/11/16.
Suppress the use of extern inline on problematic Apple configurations, as
Libc at least through Libc-825.26 (2013-04-09) mishandles it; see, e.g.,
Suppress the use of extern inline on problematic Apple configurations.
OS X 10.8 and earlier mishandle it; see, e.g.,
<http://lists.gnu.org/archive/html/bug-gnulib/2012-12/msg00023.html>.
OS X 10.9 has a macro __header_inline indicating the bug is fixed for C and
for clang but remains for g++; see <http://trac.macports.org/ticket/41033>.
Perhaps Apple will fix this some day. */

* gmalloc.c (special_realloc, calloc, mallochook): Use tail calls.
* chartab.c (make_sub_char_table): Fix size typo (Bug#15825).
This bug was introduced in my 2013-06-21 change, and caused
struct Lisp_Sub_Char_Table objects to be given too many slots,
