The way I am using it right now is that I've replaced all my 'lib :... : 
<link>static' with 'alias...'. The way I understand it is that with alias I 
get the actual objects on the linking command line and since the objects have 
no ordering issue my problem is solved. The objects are compiled just once in 
either case.

BTW: I do not really understand the problem gcc linker has with static 
libraries. The way I understand it is that *.a is just a sofisticated *.tar 
with *.o inside and since there is no ordering problem for the *.o - why there 
is for *.a??? IMHO the linker does all the work related to linking, right? So 
there is the same amout of work done for linking the exe directly from objects 
as there is for linking it from static libs, right? If this is true then it is 
IMHO just plain bug in gcc...
