+/* The GNU and SGI linkers differ in their implementation of -init and -fini.
+   With the GNU linker, there can only be a single -init option, and the
+   linker simply sets DT_INIT to that value.  gcc's initialization and
+   finalization code can go directly in .init, with the prologue and
+   epilogue of the main initialization routine being provided by external
+   object files (*crti.o and *crtn.o in this case).
+
+   The SGI linker instead accepts several -init options.  It will set DT_INIT
+   to a linker-created function (placed in .init) that calls each of the -init
+   functions in turn.  If there is any user code in .init, this linker-created
+   function will be placed after it.  Note that such user code is not treated
+   specially; it will only be called if the -init options arrange for it to
+   be called.
+
+   In theory, the SGI model should allow the crti, crtn and intermediate code
+   to go in .init, just like it can with the GNU linker.  However, doing this
+   seems to confuse the linker and triggers an internal error:
+
+      ld32: FATAL   2  : Internal: at ../../ld/mips_code.c mips_code_fixup()
+	 text section overflow!
+
+   (seen with MIPSpro 7.30).  We therefore put everything in a special
+   .gcc_init section instead.  */
