This is a somewhat ordered TODO list:

Recuring tasks:

- update versions for every tools...

Non-recurring:

- gcc-4.4

  - requires some companion libs:

    - PPL

    - CLoog

  - check that the patchset from 4.3.3 still applies

- uClinux

- add newlib (for enhanced bare metal)

  - may need heavy tweaks and bends in gcc.sh

  - try to make it generic, will help for uClibc++

  - check whether it supports running under uClinux

- uClibc++

  - see newlib, above

- Cygwin target (needs newlib)

  - so we can complie for Windows/Cygwin

- mingw32 target

  - so we can compile for Windows/Win32

- mingw32 host

  - so we can run natively under Windows/Win32 (without requiring Cygwin)

- eglibc config file
