I am using libcurl which depends on OpenSSL thus I need to link with it too.
There are binary distributions for Windows here, but I do not understand what does the character at the end of the version stands for (packages named like: Win32 OpenSSL v1.0.1b, Win32 OpenSSL v1.0.0i, …).
I might miss something but quick lurking through site/page gave no explanation about that.
What is the difference between them?
