Subject: Define bcrypt macro not available in Win 7 SDK
X-Git-Tag: v3.3.1~5^2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=bb29029333651b788131bcc34178c13dbf136ec4;p=thirdparty%2Flibarchive.git

Define bcrypt macro not available in Win 7 SDK

VS 2010 comes with the Win 7 SDK and its bcrypt.h does not define the
`BCRYPT_HASH_REUSABLE_FLAG` macro.  Provide the definition locally if
it is not available.
