I tried to compile PostGIS version 0.7.4 with make command.
I got the following error:

If you know how this problem might be fixed, list the solution below:
---------------------------------------------------------------------

I had to make the following change in
$postgresql/src/include/optimizer/cost.h:

//extern double cpu_index_tuple_cost;
extern DLLIMPORT double cpu_index_tuple_cost;

All works fine since I made that change!
