  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.

• configure : add -fPIE instead of -pie to C flags for ThreadSanitizer

  configure: add -fPIE instead of -pie to C flags for ThreadSanitizer
  
  -pie was added to C flags for ThreadSanitizer in commit
  19f251a2882a8d0779b432e63bf282e4d9c443bb. Under clang 3.8.0, the -pie
  flag causes a compiler warning and a linker error when running configure
  --toolchain=clang-tsan. Here is an excerpt from config.log:
  
  clang ... -fsanitize=thread -pie -std=c11 -fomit-frame-pointer -pthread -c -o /tmp/ffconf.A8SsaoCF.o /tmp/ffconf.JdpujQlD.c
  clang: warning: argument unused during compilation: '-pie'
  clang -fsanitize=thread -pie -Wl,--as-needed -o /tmp/ffconf.2iYA4bsw /tmp/ffconf.A8SsaoCF.o -lm -lm -lbz2 -lz -pthread
  /usr/bin/ld: /tmp/ffconf.A8SsaoCF.o: relocation R_X86_64_PC32 against undefined symbol `atan2f@@GLIBC_2.2.5' can not be used when making a shared object; recompile with -fPIC
  /usr/bin/ld: final link failed: Bad value
  clang: error: linker command failed with exit code 1 (use -v to see invocation)
  
  To be conservative, I changed -pie to -fPIE. But the documentation seems
  to imply just -fsanitize=thread is enough:
