In this example, an ANSI-conforming compiler is obliged to report a
comment which is not terminated in the file in which it started.  A 
helpful compiler would indicate the line on which the comment began.
This would have shown you the error immediately upon the first compilation.

Even though standard C does not have nested comments, a compiler may warn
about something that looks like a nested comment.  (A compiler may warn
about anything at all, so long as it does not reject or misinterpret a
legal program.)
