as the numbers of lines generated by the generation macros
(which are included in the coverage measure)
through the C preprocessor depend on the exact version
of the C preprocessor.
There is no reliable way to get a measure on it,
except by always targeting the same compiler.
So, this measure of coverage (number of lines)
is not suitable for CIT. Ratio seems also not reliable enough.
This reverts commit f45ededf8b.
