Yes.

That's strictly conforming ANSI C code.
It is using old-style (K&R) function definitions
rather than ANSI C style function prototypes,
but it is still allowed by the 1989 C standard.
GNU C (gcc) does support such code.
C++ and GNU C++ (g++) do not.

There is texinfo documentation for protoize -- it's part of the
gcc documentation.  Look for `Running protoize' in the
`Invocation' section of the GNU C manual. 
(Try the command `info -f gcc invo runn'.)
