Probably. If pressing Alt+X brings up a M-x prompt, then it's treating
mod1 as Meta.

I have both:

	shift       Shift_L (0x32),  Shift_R (0x3e)
	lock        Caps_Lock (0x42)
	control     Control_L (0x25),  Control_R (0x6d)
	mod1        Alt_L (0x73),  Alt_L (0x7f)
	mod2        Num_Lock (0x4d)
	mod3      
	mod4        Meta_L (0x40),  Meta_L (0x7d),  Meta_L (0x9c)
	mod5        Mode_switch (0x5d),  ISO_Level3_Shift (0x7c)

[From the keycodes, you can see that the "Windows" keys are Alt_*
while the "Alt" keys are Meta_*.]

If I press Windows+X (i.e. Alt-x), I get "A-x not defined." in the
echo area; Alt+X (i.e. Meta-x) gives me the M-x prompt.

I have Alt rather than Meta on mod1 so that I can use Alt-<key> for WM
shortcuts without shadowing any of XEmacs' Meta-<key> bindings. E.g. 
Alt-Tab switches between windows, while Meta-Tab does completion
within XEmacs.
