socklen_t was introduced into the Platform SDK with the August 2001
release of the Platform SDK.  

There is an alternate possible cause of the reported compilation errors:

  The compilation environment was incorrectly configured.  It is required
  that the Platform SDK environment take precedence over the Visual C++ 
  6.0 environment.

To properly construct the build environment the following commands should 
be issued to enable construction of Krb5 for all 32-bit Windows
operating systems:

  c:\program files\microsoft visual studio\vc98\bin\vcvars32.bat
  c:\program files\microsoft sdk\setenv.bat /2000 /RETAIL
  SET APPVER=4.0
  SET TARGETOS=BOTH
  SET _WIN32_IE=0x0400

replace /RETAIL with /DEBUG for debug builds.

NOTE: krb5 when built standalone uses a file based credentials cache. 
KfW should be used to construct the full set of executables and
libraries including the in-memory credential cache.

I believe the applied change should be removed.
