I'm looking for a 64-bit version of readline.dll.  Here's why.  I'm
interested in running this very cool shell called Rash.

  https://github.com/willghatch/racket-rash

The package provides a rash-repl.exe binary, but it needs either
libedit.dll or libreadline-5.dll.  Since I don't have either, I decided
the go with libreadline-5.dll, but I only find 32-bit versions online
such as the executable-package available at

  http://gnuwin32.sourceforge.net/downlinks/readline.php

When I run rash-repl.exe, I get

C:\Users\x\AppData\Roaming\Racket\7.9>rash-repl.exe
ffi-lib: couldn't open "libreadline-5.dll" ([...] errid=126)

The message is effectively "The specified module could not be found.;
errid=126)".  So I libreadline-5.dll in the same directory as
rash-repl.exe.

C:\Users\x\AppData\Roaming\Racket\7.9>dir libreadline-5.dll
[...]
07/03/2005 17:48 229.888 libreadline-5.dll
[...]

Running it again, I get:
C:\Users\x\AppData\Roaming\Racket\7.9>rash-repl.exe
ffi-lib: couldn't open "libreadline-5.dll" ([...]; errid=193)

The message is effectively "%1 is not a valid Win32 application;
errid=193", which suggests me I can't mix 32 and 64-bit code in the same
program.

So, I'm looking for a 64-bit version of readline, which seems not easy
to find on the web.

I appreciate any help.

By the way, I don't know from the top of my head any windows-specific
newsgroup for this type of question.  I suppose many here run Windows
and are users of the GNU readline library, but feel free to follow-up
with a more adequate newsgroup.  I'd follow suit.  Thank you!
