Cpp only projects failed to build when deep search for libraries is enabled.Fix to ensure Prototypes are not generated if they are already in the sketch (when Deep Search for Libraries + Accurate Prototype Insertion (Gcc-E) is enabled).Improved cleanup of teensy virtual serial port scan.Normally we would expected a change to #included source to cause recompile of all other source that uses it.
d dependanty files recompile of source code does not happen if the source has not changed but an #included source has changed.
In verbose mode a warning is displayed in the build output stating the. d dependency files will now allow caching if the source has not altered. (reminder: Non-ino cpp only projects lack automatically created prototypes + serial/wifi debugger)
