Suppose mygdiprog.cpp includes wingdi.h and uses various API calls implemented via gdi32.dll
g++ -lgdi32 mygdiprog.cpp
will throw up errors for the API calls along the lines of 'undefined reference to GetDeviceCaps@8''.
You must place -lgdi32 (which means 'link in stuff from lib\libgdi32.a') after the source file name
g++ mygdiprog.cpp -lgdi32
(This is why -mwindows makes it work, because -mwindows adds a load of -l options, and it puts them in the right place on the command line.)
