-This program reads a file containing function prototypes
-(like syscall_aix.go) and generates system call bodies.
-The prototypes are marked by lines beginning with "//sys"
-and read like func declarations if //sys is replaced by func, but:
-	* The parameter lists must give a name for each argument.
-	  This includes return parameters.
-	* The parameter lists must give a type for each argument:
-	  the (x, y, z int) shorthand is not allowed.
-	* If the return parameter is an error number, it must be named err.
-	* If go func name needs to be different than its libc name,
-	* or the function is not in libc, name could be specified
-	* at the end, after "=" sign, like
-	  //sys getsockopt(s int, level int, name int, val uintptr, vallen *_Socklen) (err error) = libsocket.getsockopt
