---------------------------------------------------------------+------------
 Sometimes, boost-build applies the inheritance of a project's attributes
 from it's parent's twice, clobber locally defined attributes.

 Attached is the smallest example I can create, and also attached is a
 patch to fix the problem.


 Run before patch:

 $ cd foo; bjam
 ...found 11 targets...
 ...updating 7 targets...
 common.mkdir ../bin
 common.mkdir ../bin/foo
 common.mkdir ../bin/foo/bar
 common.mkdir ../bin/foo/bar/gcc-3.4
 common.mkdir ../bin/foo/bar/gcc-3.4/debug
 gcc.compile.c ../bin/foo/bar/gcc-3.4/debug/test.o
 gcc.link ../bin/foo/bar/gcc-3.4/debug/test
 ...updated 7 targets...

 Run after patch:

 $ cd foo; bjam
 ...found 9 targets...
 ...updating 6 targets...
 common.mkdir baz
 common.mkdir baz/bar
 common.mkdir baz/bar/gcc-3.4
 common.mkdir baz/bar/gcc-3.4/debug
 gcc.compile.c baz/bar/gcc-3.4/debug/test.o
 gcc.link baz/bar/gcc-3.4/debug/test
 ...updated 6 targets...
