hostcheck.c: In function 'hostmatch':
hostcheck.c:64:23: error: storage size of 'si6' isn't known
*** Error code 1

The problem does not manifest on NetBSD 6.99.36 amd64.


si6 is declared inside

#ifdef ENABLE_IPV6
  struct sockaddr_in6 si6;

in function hostmatch() in file lib/hostcheck.c.  For whatever reason, on 
NetBSD the default includes define struct sockaddr_in6 whereas on DragonFly 
3.7-DEVELOPMENT they don't.  Other files in curl's lib/ such as connect.c 
explicitly include <netinet/in.h>.   On DragonFly 3.7-DEVELOPMENT including 
<netinet/in.h> in turn includes <netinet6/in6.h> which defines struct 

The following new patch file: patch-lib_hostcheck.c and
bmake makepatchsum
enabled the latest www/curl to be built and replaced on DragonFly 
3.7-DEVELOPMENT x86_64 and i386.  It might be helpful if some other BSD users 
such as for FreeBSD could provide feedback on whether generically include 
<netinet/in.h> needs to be added to hostcheck.c or whether this is a problem 
particular to DragonFly.
