+ *
+ *      Install this file as $prefix/gcc-lib/dpx2/VERSION/gcc.ifile
+ *     and comment out the lines refering to COLLECT at the top
+ *      of Makefile before building GCC.
+ *     
+ *      This file has been tested with gcc-2.2.2 on a DPX/2 340
+ *      running BOS 2.00.45, if it doesn't work for you, stick
+ *      with collect.

+ *     Ifile to link with memory configured at 0.
+ *     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 ( 0x100000 | 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.
