It seems a bit fishy that the comment in question starts on an #if line
and ends on an ordinary line.  I am not sure what the C standard says
about such cases, but I can certainly imagine that some tools might not
be very happy with that.

It looks like that code was last touched by pgindent in d747140279426607:

-#ifndef _ECPGLIB_H /* source created by ecpg which defines these symbols */
+#ifndef _ECPGLIB_H             /* source created by ecpg which defines these
+                                * symbols */

Perhaps that was a bad change, and you should make it look like

/* helpful comment here */
#ifndef _ECPGLIB_H
