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. -- Chiheng Xu
