Hello,

Building the bitcoin-qt 0.5.0rc7 client for win32 (on windows 7) has a 
little problem, qtcreator reports a conflicting type "ssize_t".

So two simple questions I guess:

1. How many bits should ssize_t be for mingw32 (types.h) ?
2. How many bits should ssize_t be for berkeley db (db.h) ?

And finally:

3. What would be a good solution to fix it ? (I could rename the type in 
db.h and modify all source code of berkeley db, but maybe there is an easier 
way ? Also I am not sure if renaming the type would help, since maybe there 
is a size conflict as well, hence questions 1 and 2 to be sure... )
