I understood the original poster as being concerned with the source
file organisation rather than library issues. The ada subdirectory
under the gcc source tree contains about a 1000 source files. Certainly I
would never organise a large project with a flat structure like this, I 
would want a directory hierarchy. I'm sure I'm not alone in this.

: files to represent a library is a perfectly legitimate design dichotomy

I don't think that is the problem, it is having lots of source files
in one directory that is objectionable.
