[Rd] problem adding gdb to RTOOLS40 on Windows

[Bravington, Mark (Data61, Hobart)]

I've not been able to install gdb for RTOOLS40 on Windows 10. The rtools installer (rtools40-x64_86.exe) doesn't seem to include gdb by default, and when I follow the instructions for adding gdb (which I tracked down at https://github.com/r-windows/docs/blob/master/faq.md) this is what happened:

<cd to c:\rtools\rtools40>
<run mingw64.exe>
$ pacman -S mingw-w64-x86_64-gdb

Something very similar happens if I try the 32bit version.

Do you have any suggestions?

 - I used to have this stuff working OK with R3.6/RTOOLS35 but have not needed to go back to C for a while. The version of gdb in RTOOLS is 7.9.1; I tried copying that gdb.exe into RTOOLS40 but it just exited instantly when I tried to run it from there. 
 
 - NB I have absolutely no idea what is meant by msys2 or pacman or any of that, I'm just following instructions... 


Thanks
Mark
