I've found where gdb is (it wasn't in the path yet), and tried your
instructions (I have never used gdb...). That is what I got:
C:\Code\geth\src>gdb runforever.exe
GNU gdb (GDB) 7.11.1
...
Reading symbols from runforever.exe...(no debugging symbols found)...done.
(gdb) run

Doesn't sound very useful to me. But GDB says "(no debugging symbols found)".
Since I compiled with "\--debuginfo", along with all the other parameters I
listed above, I would have expected gdb to find the debug info. So either it is
not located where gdb is looking (local configuration issue?) or not in the
format gdb is expecting (remember, I'm building with VC...).
So I looked into koch, and it was also there, but also not in the path, so I
copied it in the bin of my Nim installation.
That is what I got running "koch temp c runforever.nim":
C:\Code\geth\src>koch temp c runforever.nim

Looks like koch is looking fo nim.nim in the wrong place. Second attempt:
C:\nim-0.17.2>koch temp c c:\code\geth\src\runforever.nim
nim c compiler\nim
