Cygwin-3.6.9: pcon: CPR responses are broken when a non-Cygwin executable starts

[Koichi Murase]

Hi Takashi,

Thank you for the patches. For those patches to be accepted, do I need
to confirm that they fix the issue in my environment? I decided to
build `cygwin1.dll' myself. After struggling with dependencies, I
finally managed to build cygwin1.dll. I confirm that the issue is
solved after applying the three patches to the main branch (commit
209858c) of newlib-cygwin.
