-        Read-only data must reside in RAM.  
+        With older GCC compilers (at least up to 4.3.3), read-only data must reside in RAM.  
        In code generated by GCC, all data references are indexed by the PIC<sup>2</sup> base register (that is usually R10 or <i>sl</i> for the ARM processors).
        The includes read-only data (<code>.rodata</code>).
        Embedded firmware developers normally like to keep <code>.rodata</code> in FLASH with the code sections.
        But because all data is referenced with the PIC base register, all of that data must lie in RAM.
        A NXFLAT change to work around this is under investigation<sup>3</sup>.
      </p>
+      <p>
+        Newer GCC compilers (at least from 4.6.3), read-only data is no long GOT-relative, but is now accessed PC-relative.  With PC relative addressing, read-only data <i>must</i> reside in the I-Space.

  Description: Windows build issue.  Some of the configurations that use NXFLAT have
               the linker script specified like this:

-               NXFLATLDFLAGS2 = $(NXFLATLDFLAGS1) -T$(TOPDIR)/binfmt/libnxflat/gnu-nxflat.ld -no-check-sections
+               NXFLATLDFLAGS2 = $(NXFLATLDFLAGS1) -T$(TOPDIR)/binfmt/libnxflat/gnu-nxflat-gotoff.ld -no-check-sections

               That will not work for windows-based tools because they require Windows
               style paths.  The solution is to do something like this:

               if ($(WINTOOL)y)
-                 NXFLATLDSCRIPT=${cygpath -w $(TOPDIR)/binfmt/libnxflat/gnu-nxflat.ld}
+                 NXFLATLDSCRIPT=${cygpath -w $(TOPDIR)/binfmt/libnxflat/gnu-nxflat-gotoff.ld}
               else
-                 NXFLATLDSCRIPT=$(TOPDIR)/binfmt/libnxflat/gnu-nxflat.ld
+                 NXFLATLDSCRIPT=$(TOPDIR)/binfmt/libnxflat/gnu-nxflat-gotoff.ld
               endif
