Win7 enum missing in samba 3.5.3

[samba user]

Hello:

Reviewing the code in ~include/smb.h file in samba 3.5.3 and the enum for
"remote_arch_types", I have some questions:

1. Windows 7 is missing there...is there is specific reason for leaving it
out? There are references to win7 elsewhere in the code.

2. My client is Win7 but during Negotiation, it is detected as RA_WIN2K! Is
that an issue?

Thanks!
