It looks like your attempt to start the IOC is actually running the
st.cmd script using the Windows shell instead of running the IOC binary.

Windows does not understand the Unix #! line at the beginning of a
script file, although Cygwin's Bash interpreter does. Unfortunately you
are building your IOC as a Cygwin target but not using Bash as your
shell, so one simple way to solve your problem might be to start the IOC
inside a Cygwin terminal window, or to run 'bash' from the Windows
command-line. You also have to configure your PATH variable, which you
can do by sourcing the relPaths.sh file that should have been created in
your ioctest directory:
$ . relPaths.sh
$ ./st.cmd

If you want to start the IOC from the regular Windows Command shell you
have to give the name of the IOC executable as well as the startup
script filename. Your PATH variable also needs to be set properly, but
you can ask the EPICS build system to generate a batch file
(dllPath.bat) that does all that for you like the relPaths.sh file I
mentioned above which is for the Cygwin shell. Edit your
iocBoot/ioctest/Makefile and change the TARGETS = line to this:
    TARGETS = envPaths dllPath.bat
Then run 'make' in the ioctest directory, which will cause the file
dllPath.bat to be created. Running that batch file will append the
necessary directories to your PATH, and then you can start the IOC:

C:\cygwin\usr\local\epics\test\iocBoot\ioctest> dllPath.bat
C:\cygwin\usr\local\epics\test\iocBoot\ioctest> test st.cmd
