The build process only warns about .elc files which are older than their respective .el
Is there a way to tell it to recompile them?
The problem is that old .elc files (which, btw, are kept in the source tree even though I configure a separate build directory) sometimes break the build.
I currently solve the problem by using "bzr clean-tree --ignored". But this deletes ALL elc files and the price is lengthy build time...
