+ * svr3z.ifile - for collectless G++ on i386 System V.
+ * Leaves memory unconfigured at address 0.
+ *
+ * Install this file as $prefix/gcc-lib/TARGET/VERSION/gccz.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 excludes page 0 from being mapped. The value
+ * used for BLOCK should be or'd into this value. Here I'm setting BLOCK
+ * to 0x200 and BIND to ( 0x400000 | 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.
