-I what to do a static linking of libpqxx on windows with Mingw. AFAIU I should remove, -DPQXX_SHARED from win32/MinGW.mak and change libpqxx.dll to libpqxx.lib. Is that all ?
-Also I want to compile it on windows 7 64 bits, as a 32 bit library, so I can make a win32 build of my program that runs well in win 8/7/xp. What are the modification I should do in makefile to acomplish this ?
