For a static linking we need the .a files, not the .dll  that's the 
hardcore part because if there is no .a we have to import functions with 
dlltools.
That's why I think IOhannes suggested to use first the dll provided by 
PureData (pthread) at recompilation.

The third party dlls can also be provided by third party softwares (eg: 
for pdlua install lua5.3 and add luadist lib folder to PureData path).

This also should be indicated by deken during install that we need to 
add third party software for having things working.

The library dependences names can be found through the linker command 
line in Makefile prepended with "-l" characters.

Detecting could be done by referencing all system DLL provided by 
pd-extended and doing a script for detecting those libraries in linking 
command lines found in pure-data-svn/externals/myexternal/Makefile.

Unfortunately I don't have a consistent windows machine, and little 
spare time to do that, but I'd like to help windows customers to snap my 
code.
