MSYS DTK can be found as msysDTK-1.0.1.exe. After installing MSYS, get 
the following updates:

bash-3.1-MSYS-1.0.11-1.tar.bz2
coreutils-5.97-MSYS-1.0.11-snapshot.tar.bz2
MSYS-1.0.11-20070729.tar.bz2

Extract them to your MSYS folder to update MSYS, by default C:\MSYS\1.0\ 
I'm not sure if msysCORE-1.0.11-2007.01.19-1.tar.bz2 is needed or not.

Yeah, sure. Make sure you get the latest.

You should not be using GMP and MPFR from MSYS tools, they link to the 
MSYS runtime. You need to grab the source tarball and compile them to 
link to MS C runtime. The tarballs can be found at:

http://gmplib.org/#DOWNLOAD
http://mpfr.org/mpfr-current/

I'm not sure if I understand your question, do you mean configure could 
not find an appropriate GMP and MPFR installed? As above, you need MinGW 
versions instead of MSYS versions.

Also, if you plan to build the ada and gnat portion, make sure you 
already have ada support, eg gcc-ada-3.4.5-20060117-1.tar.gz. You may 
also need to disable DEP (data execution prevention) if you are using 
XP, 2003 or Vista for ada to build properly.

Glad to help out.
