It isn't cygwin specific, so w32 or windows is probably better.

I didn't find any command that can display individual selector info
"(gdb) inf dos ldt" gives
"LDT is present (at 0xc0000), but unreadable by GDB."
on my win2000 box, so I can't really try to get closer to the go32 output.
Could you please send go32 specific output?

Simply because in my experience, I always saw that
ds,es and ss are equal and that gs contains zero that is a special
selector ment to create SIGSEGV if used.

There a lots of places in win32-nat code that are i386 specific
and I don't even know if cygwin can be used to compile anything else
than i386 cpus. Maybe Christopher can answer to that one.
