I think the approved method is to use constructor functions:
void cons_func(void) __attribute__((constructor));
void cons_func(void)
{
/* Do initialisation stuff here */
}
Note that it isn't hugely well defined what order constructor
functions get called in, so be careful when calling other libraries.
Steven.
