-Description: reinforce Makefile error checking
+Description: reinforce Makefile error checking and increase verbosity
+ Initial version of the patch only reinforced Makefile error checking, but some
+ simili try/catch statement seem to be interferring with proper error
+ detection.
+ .
+ This version increases the verbosity of the build procedure by removing the @
+ commands, excepts for the beautifying `echo` statements.  In addition, error
+ checking if further reinforced, and the error handling logic of the "if"
+ statement has been modified to trigger an exit with the error status of the
+ linking command.
