1.7.10: gv invocation: Procedure Entry Point not located in DLL (Vista)

Please find my diagnostics listed below the discussion here.

I have not found any reference to a similar issue. ?Ghostview (gv) fails on
two different cygwin distros?and two different Window OSs. ?I
re-installed gv a couple of times,?but no luck. ?I have found references
to multiple versions of Ghostscript installations interfering with gv, but
that doesn't seem to apply here.

My cygcheck.out: ?Username changed to "user1"; computer name changed
to "pc1"; place changed to "America/Any_City_USA". ?Some permission
errors popped up when I ran it--didn't record them.
XWin.0.log: ?I didn't include--doesn't seem to be an X-problem.

Thanks for your help!

#Issue: ?gv exits with error code 127.
#Assuming a Linux exit code, 127 is 'command not found'. ?I observe the
#same issue on Win XP, but the rest of the tests were only done on Vista. ?

#Oddly, even though 'the command is not found,' the application
#can be located and is in my path. ?Further, it appears to be
#installed (man pages etc):

$ which gv

#gdb results shows an error code 139 (I guess) which is 'a
