[ECOS] eCos build fails when INET support is disabled

["Chris Garry" <cgarry at sweeneydesign dot co dot uk>]

eCos updated from CVS today.
Hardware: E7T
Template: net
'Samsung KS32C5000 ethernet driver package' added
'INET support' disabled in FreeBSD networking stack
'INET support' disabled in Basic networking framework

The build fails with:

arm-elf-gcc -c  -I/ecos-e/CygwinHome/ecos-build/ecos-net2_install/include -I/ecos-e/CygwinHome/repository/ecos/packages/net/bsd_tcpi

make: *** [build] Error 2

So I tried a simple fix:

diff -u -5 -b -p -r1.2 if.c

     struct sockaddr *sa = ifa->ifa_addr;
     static char _unknown[128];

     switch (sa->sa_family) {
+#ifdef INET
     case AF_INET:
         return inet_ntoa((struct in_addr)((struct sockaddr_in *)(ifa->ifa_addr)
)->sin_addr);
+#endif

     case AF_INET6:
         diag_sprintf(_unknown, "%s/%d", ip6_sprintf(IFA_IN6(ifa)),

n6_addr, NULL));
         return _unknown;

But then the build fails with:

Should it be possible to build eCos with INET disabled?

Cheers,
Chris
