GDB's `bt' implementation has nothing to do with Cygwin's capability
to walk a stack.  Cygwin only has limited capabilities there which
are used to create the stackdump file, see the stack_walk class in
exceptions.cc:
https://sourceware.org/git/gitweb.cgi?p=3Dnewlib-cygwin.git;a=3Dblob_plain;=
f=3Dwinsup/cygwin/exceptions.cc=20

If you want to create a backtrace(3) function set for Cygwin, feel
free: https://cygwin.com/contrib.html
I'm certainly not averse to patches...
