This is for sure compiler-dependent, but the "register" (and BTW
"inline) keyword were never more than a hint to the compiler which
variable should be in a register (or which function should be inlined)
and all C compilers are free to ignore that hint.
Nowadays gcc and almost all C compilers are better at register
allocation than humans (and it is quite similar for "inline" functions -
of course except the cases in kernels etc. where the hardware requires
inling).
