util.c:796: `LOCK_SH' undeclared (first use this function)

[Rob Hartill <ha...@ooo.lanl.gov>]

I just downlaoded apache-pre.tar.Z and tried to build it
on my HP UX   712/80   (if I had the chance I'd dump the HP in
favour of a Sun)


        gcc  -c -DXBITHACK -O -I/usr/include -DNSCACHE -DHPUX util.c
util.c: In function `search_nameserver_cache':
util.c:796: `LOCK_SH' undeclared (first use this function)
util.c:796: (Each undeclared identifier is reported only once
util.c:796: for each function it appears in.)
util.c:808: `LOCK_UN' undeclared (first use this function)
util.c: In function `write_nameserver_cache':
util.c:829: `LOCK_EX' undeclared (first use this function)
util.c:860: `LOCK_UN' undeclared (first use this function)
*** Error code 1

If I explicitly add    (taken from a SunOs system. A bad idea I suspect)

     #define   LOCK_SH   1    /* shared lock */
     #define   LOCK_EX   2    /* exclusive lock */
     #define   LOCK_NB   4    /* don't block when locking */
     #define   LOCK_UN   8    /* unlock */

I then end up with 

        gcc   -o httpd http_config.o httpd.o http_request.o util.o http_dir.o  http_alias.o http_log.o http_mime.o http_access.o http_auth.o  http_get.o http_post.o http_script.o http_include.o rfc931.o  http_put.o http_delete.o stream.o 
/bin/ld: Unsatisfied symbols:
   flock (code)
collect: ld returned 1 exit status
*** Error code 1


Any suggestions ?
