The description given in patch 0/3 mentions that this causes a circular dependency between the EAL and Log libraries. You should mention that here too. Until I re-read that, I didn't understand the need to move fnmatch() out of the EAL library - I was even sidetracking wildly, considering if it had to do with needing it on the host computer (for some host compiler checks).

FYI, and not important: fnmatch() is a C library function (man 3), not a System call (man 2). But obviously still O/S specific, since it is not included with the C library for Windows.
