compressed tar file with C code and gcc -v output

We’ve recently upgraded from gcc 4.4.5 to 4.8.3 and we noticed that for files
with a large amount of functions compiling with version 4.8.3 is almost an
order of magnitude slower than 4.4.5. This is even without the optimizer.
Attached is an example of such a file and the output of gcc -v with the 2
versions.

Thanks
