Aide-memoire: may need to re-install fw_gcc to make g++ work

1. It may be necessary to re-install fw_gcc[3.3].tardist after upgrading the IRIX 6.5.20m to IRIX 6.5.22m in order that g++ may work. 

2. It is suspected this is generally true for all upgrades. 

3. gcc however is not affected.

4. Possible reasons: during the installation of fw_gcc[3.3].tardist, there are a number of operations that will fix the header files...

3. gcc is not affected by the OS upgrade from 6.5.20m to 6.5.22m

4. On my O2, reinstalling fw_gcc-3.3.tardist [after deleting the previous fw_gcc-3.3.tardist] solves the problem i.e. g++ and gcc will both work without the aforesaid compiling/preprocessing problems.

It should solve the problems on my INDY too -- I still have stuff in my indy that need to be backup-ed before I reinstall fw-gcc-3.3.tardist again.
