i downloaded dvd+rw-tools-7.1.tar.gz to my 64 Bit
system and ran make.
This warning appeared
gcc -O2 -D_REENTRANT -c -o growisofs.o growisofs.c
In file included from growisofs.c:445:
mp.h: In function '__thread_wait':
mp.h:59: warning: cast from pointer to integer of different size
I read in mp.h :
{ void *ret;
if (pthread_join((pthread_t)((size_t)h),&ret)==0)
return (int)ret;
My compiler setup has: sizeof(int)==4, sizeof(void *)==8
so this is not a trivial warning.
I feel unable to evaluate the consequences of throwing
away half the bits of ret.
