format ‘%lu’ expects type ‘long unsigned int’, but argument 5 has type ‘uintptr_t’

[Christian Kujau]

Hi,

while compiling the today's git tree (e361de80bb), I get the following 
error when compiling (gcc 4.3.2, powerpc32):

----------------------------------------------------
control.c: In function ‘control_event_signal’:
control.c:3621: error: format ‘%lu’ expects type ‘long unsigned int’, but argument 5 has type ‘uintptr_t’
make[3]: *** [control.o] Error 1
make[3]: Leaving directory `/usr/local/src/tor-git/src/or'
make[2]: *** [all-recursive] Error 1

make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/usr/local/src/tor-git'
make: *** [all] Error 2
----------------------------------------------------

Reverting 7441999738e7c1b0ea94a39dd6e1f8a48043ff7d ("Add a SIGNAL event 
for control connections") seems to help. Also, changing %lu to %u in 
src/or/control.c helps too, but I don't know if this is the right thing to 
do - at all. Please check.

Thanks,
Christian.
