I'm using the exact sources of GCC from the Ubuntu archives (4.7.2), and have 
applied the necessary Debian patches.

Ahhh, I'd forgotten about --disable-bootstrap: adding that to the configure 
instructions seems to solve all the problems.  I've now successfully built and 
installed GDC 4.7, and the -j option does not disturb the build.

Just for reference, my successful configuration was:

../gcc-4.7-4.7.2/src/configure --enable-languages=d --disable-multilib 
--disable-libgomp --disable-libmudflap --disable-libquadmath 
--disable-libquadmath-support --disable-bootstrap --enable-checking=release

I'd first done a successful build with --disable-lto and without the 
--enable-checking option, so having done that, I thought I'd give these updated 
options a go.  Works fine!

Thanks so much to everyone for all the advice and patience in helping me get a 
successful build.

Best wishes,
