[Dev-C++] nul.gcda is not a gcov data file

[Serena F. <fa...@df...>]

Hello,

I have a problem with DEV C++ 4.9.9.2.
When I compile my Project there are not errors, but if I 
select "Syntax Check" from Execute menu a error appears:

[Warning] nul.gcda is not a gcov data file

What does it mean?
Where is the trouble?

Thank you for your attention.
