I have Insight 6.6. building with MinGW now for several targets 
including native. I'd like to submit the patches once they're cleaned up 
a bit - right now my patchset includes pieces for gdb as well as Insight.

Recently I had the opportunity to test debugging over a serial port for 
an arm-eabi target and found that the Insight GUI failed for this 
option. It turns out that the code which fills the drop down with 
available ports uses /dev/com<x> format which works in cygwin but not 
when compiled with MinGW where COM<x> is required instead.

Is it reasonable to replace the /dev/com parts with COM or should I 
check for cygwin and retain /dev/com there?

I've attached this part of my local patch so you can see what I mean.
