Beside that, the timestamp method cannot always be trusted.
We had problems with gnatmake which doesn't always recompile necessary
files.
The problem occurs when several files in different directories have same
name, same timestamp, and are selected with ADA_INCLUDE_PATH
timestamp and name of the file is checked, they are the sames, gnatmake
doesn't figure out that this is a different file and doesn't recompile it.
