the line wrapping might be a little off.. 

this should allow php_imap.c to support a kerberized (krb4) c-client, with the appropriate configure options.

it works with the CGI, but not the apache server module.  i'm not sure why.  we're trying to figure that part out.

I realized I should probably submit a patch that worked.. 
it works with 4.0.6, but not 4.0.7dev. The tests that 
configure (4.0.7dev) runs to check for SSL support in 
c-client misidentifies the krb4 c-client as having ssl.   I 
can configure and build 4.0.7dev if I disable the 
IMAP_CHK_SSL in ext/imap/config.m4 and rerun buildconf.

configure: error: This c-client library is build with SSL 
support. 
      
      Add --with-imap-ssl<=DIR> to your configure line. 

Check config.log for details.
config.log:

(bunch of these for the krb4 functions).  I think it's 
because it's put an -lcrypt where it doesn't belong and 
it's conflicting with some of the calls in the krb4 des 
library.  Not sure tho..

So.. here's the patch for 4.0.6.. again, it works as a cgi, 
but not as an apache server module, and i've no idea why. 
Trying to figure that part out..

Before anybody commits this patch here's a note from IMAP 
docs/FAQ:
----------------------------------------------------------
Q: Can I use Kerberos V4?
A: Kerberos V4 is not supported.  Kerberos V4 client-only contributed code
    is available as:
     ftp://ftp.cac.washington.edu/mail/kerberos4-patches.tar.Z
   This is a patchkit which must be applied to the IMAP toolkit according
    to the instructions in the patchkit's README.  I can not promise that
    this code works.
----------------------------------------------------------

And we're not going to add anything that isn't supported
by the c-client library.
