Build errors with libc++

[bhupeshpant19jan]

I am getting build errors when I am trying to compile cpprestsdk with libc++.

Currently we are compiling cpprestsdk with gnust and my task is to replace the gnustl with libc++. I have done the same for boost but I am getting these multiple errors when I am trying to compile cpprestsdk.

Seeing the below errors seems like,

1. Somehow representation of long long is different from what boost expects due to which we are getting these errors for all instantiation of templates with "long long" are failing.
2. I have screwed in some include order, I am not sure how to confirm that. I can share the list of header file include order if needed.

I could not find any such issue mentioned in existing issues, hence writing to your guys to hear your opinion on this.

Can somebody please take a look?

I can add to the above error and also state that it seems to be the REQUIREMENT now to have gcc/g++5 and with g++4 we have in house it produced the following errors:

Making gcc5 a required compiler would prove to be difficult for us because our dependency libraries libboost were compiled with gcc4 and also our Azure Storage C++ libraries as well. Mixmatching the three libraries resulted in a segv in Azure Storage C++ sdk based executable.

Please advice!
