I'm going to presume the built library file libboost_date_time-gcc-1_31.a is
in D:/boost/lib.  Please double check that.

   ^^^^^^^^^^^^ this looks wrong ^^^^^^^^^^^
            change it to the following:

 -lboost_date_time-gcc-1_31  

so your LIBS line looks like:

LIBS = -L"D:/Dev-Cpp499/lib" -L"D:/boost/lib" -lboost_date_time-gcc-1_31

Well, not actually because the -L controls the search path and you can't point
it directly to the library....

HTH,
