This is not new, I don't think, but I thought I'd check if it's a known
problem.

Running Cygwin 2.5.2 on Windows 10 (which just forced the Anniversary
update on me, various minor irritations to be overcome), I see the
following:

   > cygcheck python27.dll
  Found: C:\WINDOWS\system32\python27.dll
  C:\WINDOWS\system32\python27.dll
    C:\WINDOWS\system32\KERNEL32.dll
      C:\WINDOWS\system32\ntdll.dll
      C:\WINDOWS\system32\KERNELBASE.dll
    C:\WINDOWS\system32\USER32.dll
      C:\WINDOWS\system32\win32u.dll
      C:\WINDOWS\system32\GDI32.dll
    C:\WINDOWS\system32\ADVAPI32.dll
      C:\WINDOWS\system32\msvcrt.dll
      C:\WINDOWS\system32\SECHOST.dll
        C:\WINDOWS\system32\RPCRT4.dll
    C:\WINDOWS\system32\SHELL32.dll
  cygcheck: track_down: could not find MSVCR90.dll

But not surprisingly /c/Python27/python runs just fine, and both strace
and depends [1] report that the MSVCR90 dependency is satisfied from

  C:\Windows\WinSxS\amd64_microsoft.vc90.crt_1fc8b3b9a1e18e3b_9.0.30729.9247_none_08e394a1a83e212f\msvcr90.dll

Just a minor irritation, but I'm curious if there's an underlying
reason, or it's a bug.
