824d4062a1 compat/atomics/gcc: use __typeof__ instead of typeof 
The typeof keyword is apparently not available when using the -std=c99 option.

Fixes the use of C11 atomic functions with old GCC.

6a93b596c5 compat/atomics: add typecasts in atomic_compare_exchange_strong() 
The Solaris and Windows emulations of atomic_compare_exchange_strong()
need typecasts to avoid compiler warnings, because the functions they
call expect a void* pointer but an intptr_t integer is passed.

Note that the emulations of atomic_compare_exchange_strong() (except
the gcc version) only work for atomic_intptr_t because of the type of
the second argument (|expected|). See
http://en.cppreference.com/w/c/atomic:

_Bool atomic_compare_exchange_strong( volatile A* obj,
                                      C* expected, C desired );

The types of the first argument and second argument are different
(|A| and |C|, respectively). |C| is the non-atomic type corresponding
to |A|. In the emulations of atomic_compare_exchange_strong(), |C| is
intptr_t. This implies |A| can only be sig_intptr_t.
