/*
 *      svr3.ifile - for collectless G++ on i386 System V.
 *	Leaves memory configured at address 0.
 *	
 *      Install this file as $prefix/gcc-lib/TARGET/VERSION/gcc.ifile
 *
 *	BLOCK to an offset that leaves room for many headers ( the value
 *	here allows for a file header, an outheader, and up to 11 section 
 *	headers on most systems.
 *	BIND to an address that includes page 0 in mapped memory. The value
 *	used for BLOCK should be or'd into this value. Here I'm setting BLOCK
 *	to 0x200 and BIND to ( value_used_for(BLOCK) )
 *	If you are using shared libraries, watch that you don't overlap the
 *	address ranges assigned for shared libs.
 *
 *	GROUP BIND to a location in the next segment.  Here, the only value
 *	that you should change (I think) is that within NEXT, which I've set
 *	to my hardware segment size. You can always use a larger size, but not
 *	a smaller one.
