lcov-1.7 into third_party for code coverage on POSIX systems....

third_party/lcov/example/example.c

+/*
+ *  example.c
+ * 
+ *  Calculate the sum of a given range of integer numbers. The range is
+ *  specified by providing two integer numbers as command line argument.
+ *  If no arguments are specified, assume the predefined range [0..9].
+ *  Abort with an error message if the resulting number is too big to be
+ *  stored as int variable.
+ *
+ *  This program example is similar to the one found in the GCOV documentation.
+ *  It is used to demonstrate the HTML output generated by LCOV.
+ *
+ *  The program is split into 3 modules to better demonstrate the 'directory
+ *  overview' function. There are also a lot of bloated comments inserted to
+ *  artificially increase the source code size so that the 'source code
+ *  overview' function makes at least a minimum of sense.
