Last time I checked, the Alt key was bound by default to the same
keysym as AltGr.

Unless you have a special configuration to use this key as the A
modifier in TeXmacs you may have experienced the no-AltGr problem as

The correct behaviour is, for example, to have "Alt-a" produce the
"ae" ligature character. And "Alt-' e" should produce "é" (e acute)
assuming your keymap has dead keys).

It seems that problem was that with XFree 4.3 this did not work
correctly and the Alt key was ignored (as far as it not a TeXmacs
modifier). This patch is an attempt to fix this problem.

PS: another important thing to check is that the numeric keypad
behaves correctly with respect to NumLock, Caps-Lock and Shift. The
Shift modifier should reverse the NumLock switch and Caps-Lock should
have no effect on the keypad.
