Bill,

The debug_printf statements get printed when you run your program under
strace. (see http://cygwin.com/faq/faq.html#TOC111 )  Also, here are some
excellent tips that cgf has given on strace and debugging cygwin1.dll:
http://www.cygwin.com/ml/cygwin/2000-11/msg01469.html  (BTW, "google is your
friend" http://www.google.com/search?q=debugging+cygwin1%2Edll )

HTH,
Chris

Can someone point me to a how-to, or provide the steps, for getting set
up so that I can debug cygwin1.dll?  I want to instrument the com routines
to help zero in on a problem I am having with connecting gdb to a
simulation environment via a virtual serial port (to determine if it is
cygwin or the virtual serial port driver that is the problem).

I notice there are debug_printf statements in the code, already, but am 
clueless as to where this information gets printed.  If I at least knew 
that, I could add my own tracers, but I'd like to be able to step
through the code as well.  I finally got cygwin1.dll to compile...so what's
my next step?

Thanks,
Bill
