Re: building gdb with TUI support on Windows

Hi Eli,
Thanks for sharing.

I launch gdb from DOS, using:
1) set PATH=c:\msys64\mingw64\bin;%PATH%
2) c:\gdb\build\gdb\gdb --tui

When launching from DOS, how does it find ~/.inputrc?
Will the following work:
1. Set HOME=c:/temp/
2. populate c:/temp/.inputrc with your contents (for example)
3. Launch gdb

?

Will readline successfully locate the DOS path to ~/.inputrc ?

Thanks,
Ofir Cohen
