[sr #107532] gnutls-cli-debug [incorrecttly] reports SRP support for Windows Server 2003/IIS 6.0

[Steffen Jaeckel]

The gnutls-cli-debug should be revised in my opinion.

e.g. in testcase "Checking for version rollback bug in RSA PMS..." are also DHE
cipher suites set and if the server prefers them, the testcase will fail even if
the server hasn't that bug.

btw. that's why I wanted to build gnutls on my windows machine, to revise the
gnutls-cli-debug, but since it doesn't work for me... :/
