- Subject: [readline-mingw] backspace key and TUI size
Hi,
When compiling gdb 6.4 for native window host (minGW) I get a gdb.exe
and a gdbtui.exe where there were 2 problems.
- In the gdbtui.exe version, the TUI interface do not fit in the DOS
command window.
- In the gdb.exe version, the backspace key do not behave correctly.
I did some little modification in readline to fix both problems. I
attach the patch applied.
I've already submitted it to Chet Ramey (the readline maintainer at
bash-maintainers@gnu.org) who accepted it.
I don't know the gdb policy with readline synchronization, but I would
like it to be integrated as well in gdb distribution.
Denis
