Since you're running Cygwin, and since your shell is /bin/tcsh, your
environment probably contains

SHELL=/bin/tcsh

Per

:help startup

Windows vim sees that value of SHELL and sets 'shell' accordingly,
which it then uses whenever you execute a command that requires a
shell, such as ":!ls". However, non-Cygwin programs including
Windows vim don't understand full Cygwin paths and don't see the /bin
directory.

There are probably several ways to solve this problem, but what I've
done is to put these lines early in my .vimrc:

if has("win32") && $SHELL == "/bin/bash" && executable("C:/cygwin/bin/bash")
" Running in Cygwin.

if executable("C:/WINDOWS/system32/cmd.exe")
let $SHELL=''
set shell=C:\\WINDOWS\\system32\\cmd.exe
" Unlike other places in
" Vim, the 'shell' path must
" use backslashes. I don't
" know why.
endif
endif

You'll want to change my /bin/bash to /bin/tcsh.
