Sorry for being long.
I've tried this version too: this works. But there are compilation warnings.

Please find the test log in attachment. It includes make attempts without the 
buildconf + configure to show you why it's needed.

Cheers,

I tried it on Fedora 23 64-bit: it works providing you make/run it from a 
direct subdirectory of curl sources. I had to "buildconf" + "configure" to make 
it run.

I simply assumed that. Not sure what "buildconf" + "configure" would do.
Here is another try with a man-file check added.
