I use GDB 5.2.1 on Windows XP with SP2, and a french
layout keyboard. On GDB prompt, the keys '[', ']' and
'@' don't work, but the '#' is all right.
All these keys are dependant of "ALT GR" key, so I
think it was a readline misconfiguration, but a
.inputrc like this :
set convert-meta off
set output-meta on
set input-meta on
doesn't solve my problem. Note than the .inputrc file
is read since I set properly the HOME environment variable.
