Exactly.

Yes, there is a well-known extensively tested way of handling shell
scripts, symlinks, etc.  It's called "using a shell".  Just execve your
favorite shell (/bin/bash is most likely to be present in all installs,
and /bin/sh in Cygwin is the same as bash), and pass it the executable
path as an argument.
