Compilation of libgcrypt 1.7.5 on cygwin 64 bit fails

[Roger Qiu]

Hi Gcrypt devs,

I just tried compiling from source libgcrypt 1.7.5 (and I also tried 
earlier versions).

It always comes to this:

```

libtool: link: ranlib .libs/libgcrypt.alibtool: link: rm -fr

Please cc me as I am not subscribed to the mailing list.

All other dependencies of gnupg works on cygwin 64 bit, this is the only 
one that fails, and thus prevents building gpg2 on Cygwin 64 bit.

Thanks,

Roger
