[BBv1] Per-source configuration overrides

There's one source file (.cpp) in the Graph library that causes 
numerous compilers to loop, crash, or just plain generate bad code. The 
only workaround I've found is to be very picky about how this file is 
compiled.

- On Darwin's GCC, we need to compile without inlining, even in 
release mode.
- On MSVC 7.1, we need to compile without optimization and without 
/GR.

Is there a way with BBv1 to force these options for a particular file, 
but still be able to build "debug" or "release" for the rest of the 
files? If necessary, it's okay to put these options on an entire 
library, so long as other libraries that link against it don't pick up 
the pessimizations.

To be really specific, I'm talking about 
libs/graph/src/read_graphviz_spirit.cpp, which is build as part of the 
library libbgl-viz (see Jamfile in libs/graph/build) and linked into 
the BGL-Python bindings (libs/graph/build/python/Jamfile).

Thanks in advance :)
