    The following is the last known status of various architectures:
 
-   Known to work:	       alpha arm i386 s390 s390x sparc sparc64
-   Works static, not shared:   mips(*) arm-thumb
+   Known to work:	       alpha arm i386 s390 s390x sparc sparc64 x86_64*
+   Works static, not shared:   mips* arm-thumb
    Need crt0.S updates:	       ppc 
    Missing setjmp:	       ppc64
-   May or may not work:	       x86_64
    Need porting work:	       cris ia64 m68k mips64 parisc sh
 
-   (*) = Linker problem; might work with fixed linker
+   x86_64: requires a kernel header patch (to be created)
+   mips:   linker problem; might work with fixed linker
 
    Shared library support for sparc/sparc64 requires binutils 2.13.90.0.4.
