OK, I see I was unclear.  This list provides help to those who are using 
the Cygwin DLL or one of it's distributed packages as installed by 
"setup.exe" from one of the advertised (<http://cygwin.com/mirrors.html>)
mirror sites.  Discussion of other installations, configurations, or 
third-party packages are considered off-topic here.  I didn't just dream 
this rule up.  It's stated as part of the charter of the "cygwin" list
found at <http://cygwin.com/lists.html>.  So the fact that you're asking 
a question about GNUARM here really makes the question off-topic.  That's
why I was gently prodding you to what would hopefully be a better source of
information on this topic.   Not that you might not find the answer to your
question from someone on this list or in it's archives.  It's just that
given the list's scope, this is less likely.

As to your specific points above, you would only be getting complaints
about _impure_ptr if you have another, ancient cygwin1.dll loaded and/or
on your disk somewhere.  The 'putpkt' seems to be a 'gdb' issue.  You
might have some luck looking at the GDB site <http://sourceware.org/gdb/>
too.

HTH,
