Returns a platform-specific description of the host system for the Tk widget called window. Where this is X11 of some form, the string is highly likely to include a description of the exact version of the protocol in use.

Under "Windows 10 Pro 22H2 64-bit build 19045.6218" and "Windows 10 Enterprise 22H2 64-bit build 19045.6216" the results of "winfo server ." are different over the used Tcl/Tk versions!
Under ActiveState with ActiveTcl 8.6.4.1, BAWT 2.3.1 with Tcl/Tk 8.6.13 and BAWT 3.0.1 with Tcl/Tk 8.6.16 the result is correct with "Windows 10.0 19045 Win64" or "Windows 10.0 19045 Win32".
Under BAWT 3.0.1 with Tcl/Tk 9.0.1 the result is "Windows 0.1 0 Win64". That is not correct.
I can't see the cause for this behavior. Maybe the rule-set for (regular?) expressions is now wrong (integer problem)?
BTW, "parray tcl_platform" is correct (and same) on all tested OS's and Tcl/Tk versions.
