Yes I confirm GDB HEAD builds fine with GCC trunk, on compile
farm gcc17 (bi-quad x86_64):

guerby@gcc17:~/build-gdb$ gcc --version
gcc (GCC) 4.4.0 20090228 (experimental) [trunk revision 144486]
guerby@gcc17:~/build-gdb$ ../gdb-head/configure --prefix=/n/17/guerby/install-gdb-20080228 --disable-nls
guerby@gcc17:~/build-gdb$ time make -j 8; echo $?
make[1]: Leaving directory `/home/guerby/build-gdb'

It looks like GDB make -k check is not parallelized so it will take
a while more to have testresults :). 

Jakub contributed last year some Makefile smartness to parallelize make
check for GCC may be the same kinf of trick would work for GDB since I
see many subtargets in gdb/
