address@hidden:/usr/local/tmp/auctex$ git grep -i gswin..c
ChangeLog-preview:      `system-type', using "GSWIN32C.EXE" on `windows-nt'.
ChangeLog-preview:      gswin32c.exe as a problem source.
ChangeLog-preview:      * doc/wininstall.texi: Add note about `gswin32c.exe'.
configure.ac:   AC_CHECK_PROGS(GS, gs GSWIN32C.EXE, NONE)
configure.ac:   EMACS_LISP([[lispGS]],[[(if (member dir (list \"NONE\" (if (eq 
system-type 'windows-nt) \"GSWIN32C.EXE\" \"gs\"))) \"\" \`(defvar 
preview-gs-command ,dir))]],-no-site-file,[[dir]],[["${GS}"]])
doc/wininstall.texi:gswin32c -h
doc/wininstall.texi:GS="@var{drive:/path/to/gswin32c.exe}" ./configure @dots{}
doc/wininstall.texi:should work for this purpose.  @file{gswin32c.exe} is the 
usual name for
preview.el.in:      (executable-find "GSWIN32C.EXE")
address@hidden:/usr/local/tmp/auctex$ 

So in a way yes.  What a stupid naming scheme.  Maybe one should look
for gswin32c before gswin64c in case both are installed in a 32 bit
system.  But I don't have an actual clue about Windows systems.
