Oops, should have gone to the list

BTW, talking about the unit testframework: It doesn't build here by default:

$ make -f makefile.unix test_bitcoin  USE_UPNP=

g++ -static  -o test_bitcoin  obj/test/test_bitcoin.o -Wl,-Bstatic -l
boost_system -l boost_filesystem -l boost_program_options -l boost_thread -l
db_cxx -l ssl -l crypto -Wl,-Bdynamic -l gthread-2.0 -l z -l dl -l pthread
-lboost_unit_test_framework
/usr/lib/gcc/x86_64-linux-gnu/4.4.5/../../../../lib/crt1.o: In function
`_start':
(.text+0x20): undefined reference to `main'
collect2: ld returned 1 exit status
make: *** [test_bitcoin] Error 1

Two ways to fix this:

1) Add #define BOOST_TEST_DYN_LINK  to the top of test_bitcoin.cpp. This is
needed for dynamic linking.

2) Link boost_unit_test_framework statically

test_bitcoin: obj/test/test_bitcoin.o
        $(CXX) $(CFLAGS) -o $@ $(LIBPATHS) $^ $(LIBS) -Wl,-Bstatic
-lboost_unit_test_framework -Wl,-Bdynamic

(yes, it needs the switch to dynamic again at the end, otherwise libgcc will
be linked statically which results in an error ...)
