That is not guaranteed to filter only the desired lines (if a configure 
parameter would end in "gcc", or there is "gcc " in the path GCC was 
compiled in).
The reason I proposed "gcc --version | head -n1" was that the output is 
only dependent on the GCC source, whereas "gcc -v | grep" also depends 
on the system configuration.
Btw, what is the reason for ".*" in the first place?
