Re: how to know the flags of pkcs7_sign at receieing side

Re: MSVC2005 project file for openSSL

This is CC'd to the openSSL ML as the question was raised there a while ago and I promised I'd get back to that. Sorry for the delayed response - as we are migrating our dev. environment to facilitate multiplatform builds from MSVC2005 it took quite a while
