I'm not convinced I have the same *h *cpp source code as you but I'm mostly sure I have the same IDE and compiler.

Make sure there is only one MQTT.h / MQTT.cpp on your machine

This is my pubsubclient-master folder
Move (don't rename) your folder to a safe place, unzip my files in ...\Arduino\libraries, and test

Result
There are far fewer compile errors but still there is probably a hidden dependency on a file containing type defs that results in the compile error below.
My compiling is with Windows 7 pro 64 bit ....Are you compiling with Unix?

For some reasons, you may have an outdated WString.h
Make sure you only have one WString.h/WString.cpp on your machine
Please replace WString.h/WString.cpp with mines
They should be burried there: C:\Users\...\AppData\...\Arduino15\packages\esp8266\hardware\esp8266\1.6.5-...\cores\esp8266\
Let me know the outcome, I am really eager to have this matter solved

FWIW, this page may be of interest

- Mon Sep 28, 2015 9:29 am #30048 Most IDE's are unduly convoluted ( way too many files and interdependence between files) Arduino is no exception. I come from a PIC development system in which stable coding encourages few *h files and few inter dependencies between *h and *c files.
In that regard Arduino provides a window on the dependencies actually used but can only point out the inconsistencies via error in the compilation.
Below is the verbose information from the failed compile.
Action
Please replace WString.h/WString.cpp with mines
They should be burried there: C:\Users\...\AppData\...\Arduino15\packages\esp8266\hardware\esp8266\1.6.5-...\cores\esp8266\...done
