Obsolete installation instructions and inconvenient CVS HOWTO

[Reichelt <reichelt at igpm dot rwth-aachen dot de>]

Hi Gerald,

first, the information on the web page
  http://gcc.gnu.org/install/configure.html
is a a little bit obsolete. From a recent discussion with DJ Delorie:

Me:
>> According to the fifth paragraph of
>> http://gcc.gnu.org/install/configure.html

>>

>> Or did I miss something?

DJ Delorie:

Could you please update the information?

Second, it would be nice if the paragraph about 
  "CVS tags and checkouts"
in
  http://gcc.gnu.org/cvs.html
would mention how to check out the current 3.2-branch instead of the
3.0-branch:

"You can check out the latest version of the GCC 3.0 release branch with
the following command: cvs -z 9 co -rgcc-3_0-branch gcc".
