Problems with compilation under MinGW

[Dmc]

I am getting some bad linking issues when compiling with MinGW. I
assume it is the result of the top of the following error messages:

Hi Dmc

I build curlpp by i686-w64-mingw32-gcc ( cross compile in Debian/GNU Linux).

Please see attached patch.

> To curlpp developper ?

If right and available, please merge this patch into curlpp Upstream...
