I've upgraded to GCC 2.2.2d yesterday. By reading FAQ for GCC and FAQ for
Linux, I still have some questions:

1. The FAQ says I should get rid of gcc older than 2.2.2. But how about
   2.2.2 itself? With 2.2.2 and 2.2.2d together, I don't have much more
   hard disk space left. Should I used the method suggested in Linux FAQ,
   which means I need to use some device to detect the depending version
   of all the binaries compiled by GCC and then recompile the older ones?

2. Having only 2 introductory C books on hand and a simple GCC man page,
   Should I keep all the stuffs in the following 3 directories if I don't
   write C programs myself and just use GCC to compile new utilities and
   use them?

       /lib/*.*
       /usr/lib/...../i386-linux/2.2.2d/*.*
       /usr/lib/...../i386-linux/2.2.2d/shared/*.*
