successfully, the executable will not run:
$ /usr/local/zsh-2009-03-11/bin/zsh -f
$ echo $?
127

My guess is that some kind of runtime dependency is missing, but:

$ cygcheck /usr/local/zsh-2009-03-11/bin/zsh.exe
C:\cygwin\usr\local\zsh-2009-03-11\bin\zsh.exe
  C:\cygwin\bin\cygwin1.dll
    C:\WINDOWS\system32\ADVAPI32.DLL
      C:\WINDOWS\system32\KERNEL32.dll
        C:\WINDOWS\system32\ntdll.dll
      C:\WINDOWS\system32\RPCRT4.dll
        C:\WINDOWS\system32\Secur32.dll
  C:\cygwin\usr\local\zsh-2009-03-11\bin\libzsh-4.3.9-dev-1.dll
    C:\cygwin\bin\cygiconv-2.dll
    C:\cygwin\bin\cygncurses-9.dll
    C:\cygwin\bin\cyggcc_s-1.dll

Just for grins, could you rebuild zsh against libncurses9 -- but this
time use gcc3?  cygiconv-2 and cygncurses-9 use the static gcc-3.4.4
libgcc.a, but you are apparently using the gcc-4.3.2 shared libgcc.

I just wonder if that presents an incompatibility that could explain
what you are seeing.

Thanks for replying, Chuck.

As I mentioned in the initial email, I had already done just that.  Just 
to be sure, I did it again, with the same result:

$ cygcheck ./zsh.exe
C:\cygwin\usr\local\zsh-2009-03-11\bin\zsh.exe
  C:\cygwin\bin\cygwin1.dll
    C:\WINDOWS\system32\ADVAPI32.DLL
      C:\WINDOWS\system32\KERNEL32.dll
        C:\WINDOWS\system32\ntdll.dll
      C:\WINDOWS\system32\RPCRT4.dll
        C:\WINDOWS\system32\Secur32.dll
  C:\cygwin\usr\local\zsh-2009-03-11\bin\libzsh-4.3.9-dev-1.dll
    C:\cygwin\bin\cygiconv-2.dll
    C:\cygwin\bin\cygncurses-9.dll

$ cygcheck ./libzsh-4.3.9-dev-1.dll
C:\cygwin\usr\local\zsh-2009-03-11\bin\libzsh-4.3.9-dev-1.dll
  C:\cygwin\bin\cygwin1.dll
    C:\WINDOWS\system32\ADVAPI32.DLL
      C:\WINDOWS\system32\KERNEL32.dll
        C:\WINDOWS\system32\ntdll.dll
      C:\WINDOWS\system32\RPCRT4.dll
        C:\WINDOWS\system32\Secur32.dll
  C:\cygwin\bin\cygiconv-2.dll
  C:\cygwin\bin\cygncurses-9.dll

How can I ascertain what entry point is not being found?
