For me to understand, does this mean we never will be able to start the
profiler under Cygwin Emacs?
I wouldn't say "never". According to the Cygwin API documentation
(https://cygwin.com/cygwin-api/std-notes.html), "getitimer and setitimer only
support ITIMER_REAL for now." I'll ask on the Cygwin list about the possibility
of supporting ITIMER_PROF.
If what Corinna suggested on the Cygwin list doesn't fit the bill,
perhaps consider reusing the w32 code, which emulates setitimer, and
does support ITIMER_PROF well enough for the profiler to be usable.
