Average file size is not relevant here. You should consider how many
code are in files that are big. In gcc/ sub-directory, there are
about 600 source files(.c and .h). 63 of them (10%) exceed 100 KB,
which contribute over 50% of the total source file size of the
directory. 75 of them(13%) is between 50 KB to 100 KB, which
contribute 25% of the total source file size of the directory.
The rest, 440 or so of them, is below 50 KB, which contribute 75% of
the total source file size of the directory. Some of this files are
so small that some merging is needed.
So, I can say, most of the GCC source code is in large files.
And this also hold for language front-ends.
