Stripping out all the warnings and the stupid white space, you have this:

librariesGSM\GSM3SoftSerial.cpp.o (symbol from plugin): In function `GSM3SoftSerial::spaceAvailable()':

C:\Program Files (x86)\Arduino\hardware\arduino\avr\cores\arduino/main.cpp:46: undefined reference to `loop'

You can NOT use SoftwareSerial in any sketch that uses GSM, because it implements a version of software serial that uses all the same resources that SoftwareSerial needs.
