Actually, if you read the signal(7) man page you'll see that the POSIX 
specification is pretty loose with a number of the signal value 
definitions.  SIGUSR1 can be 30, 10, or 16.  For example, x86-based 
Linux, which could be considered a relatively non-obscure operating 
system, defines SIGUSR1 as 10.  In fact, the only flavors of Linux that 
use 30 for SIGUSR1 are DEC Alpha and SPARC.  And since you asked, SIGBUS 
can be either 7 or 10.
