Summary:                    Coverage counts 0 lines when path too long
Description: 
If the path to the .gcov files to be generated becomes to long, there is no
error message, the LOC counters are just 0.

Steps to Reproduce: 
Dropping the attached files in a directory like '/home/pascal/ctest-cov' and
running
mkdir d && cd d && cmake .. && make && make ExperimentalTest && make
ExperimentalCoverage

yields
	Covered LOC:         2
	Not covered LOC:     0
	Total LOC:           2

But when using 'abcdefghijklmnopqrstuvwxyz01234567890123456789' instead of 'd', 
it yields
	Covered LOC:         0
	Not covered LOC:     0
	Total LOC:           0


Additional Information: 
cmake version 2.8.5
ctest version 2.8.5
c++ (Ubuntu/Linaro 4.6.1-9ubuntu3) 4.6.1
gcov (Ubuntu/Linaro 4.6.1-9ubuntu3) 4.6.1
