I have no idea what knowledge you have. It looks like you don't know
what makefiles and configure is. These two are freeciv independent.

The generated makefiles will create archives (of .o files) for each
directory. For example will common/libcivcommon.a will contain all
files common/*.o. Later all these archives are linked together with
the main file (the one which has the main function) like so:

  gcc -g -O2 -Wall -o civserver civserver.o ../common/libcivcommon.a
  ../ai/libcivai.a ./libcivserver.a ../common/libcivcommon.a
  ../ai/libcivai.a ./libcivserver.a -lreadline -lncurses -lm -lz

The step with the archives isn't strictly necessary. You can just link
all *.o files and get the same result:

  gcc -g -o civserver ../common/*.o ../ai/*.o *.o ../common/aicore/*.o
  -lreadline -lncurses -lm -lz

Have you read http://www.freeciv.org/windows/ and the general
http://www.freeciv.org/startguide.html? Till which point did you get?
