Subject: Remove register keyword from public header files
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The following code

  void f(void)
  {
    register int i;
  }

gives a warning with GCC and -std=c++17

  test.cc: In function ‘void f()’:
  test.cc:3:15: warning: ISO C++1z does not allow ‘register’ storage class
  specifier [-Wregister]
    register int i;
		       ^

and clang with -std=c++14

  test.cc:3:3: warning: 'register' storage class specifier is deprecated
  and incompatible with C++1z [-Wdeprecated-register]
    register int i;
    ^~~~~~~~~
  1 warning generated.

Remove the use of the register keyword at least in the public header
files for C++ compatibility.

Close #3397.
