I already fixed that in my current version of virtualpok, but Janek's
patches were created against his version from April.

He already has the new version.

I maintain an own linkcmds in virtualpok, as I added a 0x1000 offset to
the start of the binary. It confused me to see some strange code in GDB
when the actual issue was a NULL pointer.
However, this offset led to other issues with debugging pok+rtems, so I
am thinking of dropping this again. Meaning, using pc386/startup/linkcmds.

Cheers,
Philipp
