Boost-build project inheritance broken

[Brian Freyburger <bfreyburger@…>]

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...

Thanks for the patch. Applied in r65165. This was actually checked in a few days ago, but Trac ignored the request to updated the ticket.
