Hi!

There’s one annoying thing, I can’t help it. Sometimes we rename our
header files, and when we try to build the project, the source files,
which included those headers aren’t rebuilt. This leads either to
linker errors or even to incorrect binaries in the worst case.

Is this behaviour indentional? Should the source file with missing
includes be declared as outdated?

Sample:

/////////////////// foo.cc ////////////////////////
#include "Test.hh"
int main() { return 0; }

/////////////////// Jamroot /////////////////////
exe foo : foo.cc ;
