MIT Kfw SDK w/ Cygwin? Trying to build OpenSSH w/ GSS-API on Cygwin...

[Nicolas Williams <Nicolas.Williams@ubsw.com>]

I'm trying to build OpenSSH (2.9p2, for now) with Simon Wilkinson's
patches that implement the external-keyx / GSS-API extensions.

Specifically I wish to use Kerberos V as the GSS mechanism.

That means picking Heimdal or MIT krb5 as the Kerberos V implementation.

I started with MIT krb5, specifically Kfw (Kerberos for Windows).

Kfw is compiled with MSVC++ (all C).

*FAQ check: it is supposedly ok to mix Cygwin with MSVC++ built (C only) DLLs*

After writing the necessary autoconf checks for Kfw (library names
differ) and dealing with making sure that _WIN32 is defined where the
Kfw headers are included, I've gotten as far as getting a successful
link of ssh.exe. But it crashes with SIGSEGV and I'm still trying to
get a stack trace.

Looking at the dependencies of the Kfw DLLs I see that there is a
dependency on MSVCRT.DLL.

*FAQ check: MSVCRT.DLL and cygwin1.dll are mutually exclusive*

But the dependency on MSVCRT.DLL by the MIT Kfw DLLs is indirect.

QUESTION: Does the MSVCRT.DLL/cygwin1.dll mutual exclusivity apply in
          this case?

If so, then I'll give up on Kfw now and try Heimdal - unfortunately that
probably means giving up on Leash32.

QUESTION: Does the MIT krb5 stuff build on Cygwin? Kerbnet appears to
          have died some time ago...

Thanks,

Nico
