error in c program for cgi

When compiled and placed in the cgi directory, the code below generates a
server (netbsd/apache) error. The directory & mintst.cgi permissions are
u=rwx g=x o=rx and have, if memory serves, been used previously with
success.

Any suggestions regarding the cause of error are most welcome.

Hul

---c code
int main()        /* mintst.c */
{
        printf("Content-type: text/html\n");
        printf("<html>\n");
        printf("<head><title>Title of mintst.c</title></head>\n");
        printf("<body>\n");
        printf("<tt>\n");
        printf("<pre>\n");

        printf("MINTST is complete\n");

        printf("</pre>\n");
        printf("</tt>\n");
        printf("</body>\n");
        printf("</html>\n");
        exit(0);
}

---html code that links/calls mintst.cgi
see mintest <a href="http://www.panix.com/~ht/pcgi/mintst.cgi">[mintest]</a>

<tt> is an inline element and hence can not contain a block level
element. like <pre>. Switch the nesting of these two elements.

The rest of the your problem has nothing to do with HTML. I'd suggest a
CGI or a C authoring group instead.

You need a blank line between the HTTP header and the HTML document.
(You also appear to be missing the Doctype).
