srcdir == objdir build issues

[Dara Hazeghi]

Hello,

there seems to be a fair number of people who like to build gcc with a 
straight ./configure && make && make install. Unfortunately, this 
doesn't seem to work a fair bit of the time, as is seen by the 10-20 
bug reports we have about it in GNATS. The documentation 
(http://gcc.gnu.org/install/configure.html) claims it _should_ work but 
is not tested much. So my question is do we in fact support this, and 
is it something which will receive regular testing?
