[openssl-users] GSCheck fails for Windows 32build 'libeay32.dll' library

[Jakob Bohm]

If GSCheck is just a tool to check if you remembered to build
code with the buffer overflow checks that Microsoft C can
insert, then you should just treat this as a warning that the
tool doesn't know how to check code from other compilers (in
this case the manual work of the OpenSSL team).
