Remove register keyword from public header files
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.
