SIGBUS -> SIGSEGV

Hi there,

while trying to compile tcl within Haiku, the build process
failed in a switch case on SIGBUS saying that it was already
defined a few lines above, where actually the case SIGSEGV
was. So I looked up in the Haiku code and found the following

#define SIGBUS      SIGSEGV /* for old style code */

What does exactly old style code means? Is this still needed?

Regards,
