+This issue requires the following.
+1. Generated source file which outputs 2 (or more) files
+2. Action string gets scanned providing only compiler as part of implicit scan
+3. Generated file gets built. Without the bugfix only the first target's .implicit list is cleared.
+4. builder/executor/action gets tried again and implicits scanned. 2nd to Nth targets end up
+   with the compiler at the beginning of the implicit list and the rest of the scanned files added to that list.
+5. That bimplicit gets saved into sconsign
+6. Second run loads sconsign, now with generated file present a regular implicit scan occurs. This yields 2nd through
+   Nth target's implicit lists changing when compared to SConsign's which have been loaded.
+7. This forces rebuild of source file and this propagates to massive recompile
