Which CNC Mill Accepts G-Code which is most similar to LinuxCNC?

I'm confronted with a post-processor which outputs drill-cycles which do not drill the first hole in the array.  All the other ones but not the first.

This may not be anyone's fault but mine. I modified a Fanuc NC- Gpost options file to work with LinuxCNC and for the most part it does, but I'm getting tired of manually editing the g-code to get the first hole.

I had understood that the original EMC2 G-Code was evolved in accordance with a national standard.  Is there any chance that any modern machine controller uses the same basic system?

If this question isn't clear, let me know and I'll try to do better.

I think I found the problem. PTC had published a config file for Gpost which was intended for Fanuc 3-Axis. Buried in it was a toggle which allowed/ or didn't allow reuse of a set of coordinates. Apparently this is intended to deal with coordinates which are stacked in a register such that if you access the register, the next set is dispensed and is gone.
My situation required that a set could be used again in succession.

changing my config to allow this fixed the problem.

I'll check to see if Tormach is supported.
and thanks for the idea.
