Within Emacs, `exec-path' could help:

,----[ C-h v exec-path RET ]
| exec-path is a variable defined in ‘C source code’.

On Windows, TL comes with a smaller, hidden version of Ghostscript.  See
the file:

f:/Program-folders/TeXlive2015/tlpkg/tlgs/README.TEXLIVE

You can access this version of Ghostscript through `rungs'.  Try

rungs --help
