I think this is in response to a comment I made on IRC. Giuliano said
that if a project has a very large file that dominates the total build
time, the file should be split up into smaller pieces. I said  "GCC
can't restructure people's code. it can only try to compile it
faster". We weren't referring to code transformations in the compiler
like re-ordering functions, but physically refactoring the source
code.
