Re: gcc4.8.0 build and package (was: gcc 4.8.0 Ada error)

Hi All, I need your input with regarding the direction of building and 
packaging gcc 4.8.0.

You can find some more discussions from 
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=56909

Please let me know which option you'd like to go, or you may have other 
suggestion. Thanks.

1. build with '--with-arch=i686 --build=mingw32'
   this will force arch to i686 ONLY

2. build with '--build=i686-pc-mingw32'

   this is the suggested workaround by gcc team, however, our old v4.7.2 
has lib installed to \MinGW\lib\gcc\mingw32\4.7.2 (as --build=mingw32)
but now new v4.8.0 build will install lib to 
...\gcc\i686-pc-mingw32\4.8.0. This also applies to libexec dir too. 
Also the bin\mingw32-*.exe will become bin\i686-pc-mingw32-*.exe

As my limited tests, gcc looks fine with above dir/file name changes but 
I don't know if this may break other (e.g. MSYS) part of MinGW.

3. exclude Ada from v4.8.0 build and package

   this leaves our Ada package as 4.7.2
