Issues with v1.95-4.2 (current Windows binary)

[Janko Thyson]

Hi Duncan,

I ran into an issue in combination with devtools that must have popped up starting with RCurl v.1.95-4.2: r-lib/devtools#532

As there's no Windows binary for v1.95-4.3 yet, I tried to install from source, but failed due to libcurl being missing. Could you tell me which version of libcurl I would need for Windows 8.1 (64 bit) and where exactly this needs to go in order to compile the package from source?

Thanks!
