Import of unmodified (but trimmed) gcc-2.7.2. The bigger parts of the

non-i386, non-unix, and generatable files have been trimmed, but can easily
be added in later if needed.

gcc-2.7.2.1 will follow shortly, it's a very small delta to this and it's
handy to have both available for reference for such little cost.

The freebsd-specific changes will then be committed, and once the dust has
settled, the bmakefiles will be committed to use this code.

+ *      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.
