did you worked this around already? If not, I have a very crude idea ---
definite kluge. Each toolset defines a rule called "C++-action", which 
set ups build actions. You can tweak that rule for a given toolset, so 
that it notices when the problematic file is compiled and changes 
options appropriately. This *completely* bypasses all the build system 
machinery, but per-source requirements can't be added to V1.

To determine when you're compiling problematic file, you can look at the 
first argument of the rule. For example, you might be looking for

<dir1/dir2/library1/.....>file.o

This is only an idea, not 100% finished recipe. Feel free to ask if you 
run in any problems with it.
