Summary:                    c99 snprintf usage
Description: 
Raptor checks carefully for a c99 snprintf, but in src/raptor_locator.c assumes
that one is available by doing:
bufsize += snprintf(NULL, 0, " column %d", locator->column);

snprintf(NULL,0,...) causes a segfault on OSF/1, and returns incorrect results
on HP-UX, AIX 5.1 (both return 0) and Solais 9 (returns -1).

Additional Information: 
Attached patch works around the issue ":<integer> column:<integer>" is never
going to be larger than 4096 bytes (or even 1024 bytes).
