[openssl.org #1858] OPENSSL_NO_SOCK build related patch for the 2.8 stable branch.

[Jurko Gospodnetic via RT]

   Hi.

   Attached patch for the 2.8 stable branch disables some unneeded SSL 
socket BIO functionality (crypto/bio/bss_sock.c) in case the 
OPENSSL_NO_SOCK macro is defined. Similar #ifndef/#endif already exists 
in a related crypto/bio/b_sock.c module.

   Without this patch OPENSSL_NO_SOCK builds cause failures due to 
warnings when building on Windows. Tested on Windows XP SP3, with the 
MSVC 9.0 SP1 compiler.

   A similar patch should be applied to the CVS HEAD as well.

   Hope this helps.

   Best regards
     Jurko Gospodnetić


  Patch disabling unneeded SSL socket BIO functionality in case OPENSSL_NO_SOCK
is defined. Without this patch compilers will report warnings due to certain
functions used in this module not being defined.
