Thanks, Greg, for the pointer!

Unfortunately, unless I'm doing something wrong, it isn't due to
proc_retry:
thrall AT pc1163-8413-xp ~
$ echo $CYGWIN
thrall AT pc1163-8413-xp ~
$ cygcheck /bin/ash.exe -v
C:\cygwin_1.7\bin\ash.exe
C:\cygwin_1.7\bin\cygwin1.dll
C:\WINDOWS\system32\ADVAPI32.DLL
C:\WINDOWS\system32\ntdll.dll
C:\WINDOWS\system32\KERNEL32.dll
C:\WINDOWS\system32\RPCRT4.dll
<5 more copies of the DLL info>
thrall AT pc1163-8413-xp ~
$ export CYGWIN=3Dproc_retry:1
thrall AT pc1163-8413-xp ~
$ cygcheck /bin/ash.exe -v
C:\cygwin_1.7\bin\ash.exe
C:\cygwin_1.7\bin\cygwin1.dll
C:\WINDOWS\system32\ADVAPI32.DLL
C:\WINDOWS\system32\ntdll.dll

Oh well, at least I learned something :)
