Ok, the basic idea used to be that when linking the DLL also it's
equivalent "import library", 'libmydll.a' for the 'libmydll.dll'
would be created. Whether the '-shared' does this automatically is
unclear. For instance at :

there is the phase "3" :

# Creating the dll

gcc -shared -o message.dll dll.o -Wl,--out-implib,libmessage.a

for creating the import library at the same time with the DLL

When linking executables which will use the DLL, the import lib
will be used, NOT the DLL itself!
