mingw or msvc version

["Andrey Seredin" <odissey@xxxxxxxxxx>]

Tell me, please:
What the version of mingw was used for build libssh-0.7.2-mingw.zip ?
What the version of msvc was used for build libssh-0.7.2-msvc.zip ?
and how to know what versions of zlib, openssl and gcrypt were used for build ?

Thanks!
