No, that means that the batch file is invoked, not the command.  What
happens when you open a cmd.exe window and type "c:\cygwin\cygwin.bat"?

It is different, unless you invoke bash with the exact command-line
options it has in cygwin.bat.

AFAICS, ls does *not* depend on SECUR32.DLL.  What does "cygcheck
/bin/ls.exe" show?
