Yes obviously socket support is present in iOS SDK 7.1, I’ve checked :-)

I noticed this:
checking if socket can be linked... yes
checking if socket is prototyped... no
checking if socket might be used… no

or this:

checking sys/time.h presence... no
configure: WARNING: sys/time.h: accepted by the compiler, rejected by the preprocessor!
configure: WARNING: sys/time.h: proceeding with the compiler's result

In my humble opinion it seems preprocessor iOS is using is not compliant with curl config file.
