[MinGW-dvlpr] GCC 4.5 XML manifests for mingw-get

[Cesar S. <ces...@gm...>]

Hello,

I've been working lately on the mingw-get XML manifests for gcc 4.5.0
and I think they are currently in a good shape. This includes the 
missing manifests for the gcc 4.5.0 dependencies as well (mpfr, mpc, 
pthreads-w32).

I'll begin committing them to CVS for review.

Keith, do you have any work in progress on this front? I'll gladly merge 
it in.

I would like an opinion on the following:

1) For now, I kept the entries for gcc 3.4.5. Should I remove 3.4.5 
altogether?

2) Otherwise, should the gcc package be split into gcc3 and gcc4?

3) Should mingw32-base be renamed to mingw32-gcc?

Regards,
Cesar
