Voloyda,

Thanks. I'm not sure what b2 is, however. It doesn't seem to exist in 
our executable directory. Our bjam does have a --debug-building option; 
it also produces a lot of data (302K lines) and and it's not clear what 
to extract from it. I tried this as a first approach:

bjam -a -k -n --debug-building ... | egrep -o '[@%]Jamfile<[^>]*>' | sort -u

but only got the Jamfile for the targets I passed. The 'Building target' 
lines look like they might have what I need in them (including one 
project that the -d+12 output missed) but I'll have to experiment with 
is more.
