Thanks for your update & write-up, looks promising :)  I agree with your 
approach of trying to find the most lightweight C logger that does the job, 
just two quick questions about your work:

(1) do you plan to mainly using the logger to write to files and an equivalent 
of `stderr` consistently across multiple platforms or do you also plan to use 
it to replace some of the handling that's currently done within FreeType (like 
checking + parsing log levels + components, etc) with calls to that library?  I 
believe it would be especially interesting if we managed to move some of the 
components handling out of FT and into that external piece.  Not sure however, 
if any of these libraries have a somehow direct mapping of how components 
(modules) are used for tracing within FT currently (essentially, all 
components/modules can be configured with their own trace level).

(2) have you looked into log4c at any point?  Not saying it is what FreeType 
needs but something that worked reasonably well for me a while ago;  might be a 
lot bigger than what we need or have other downsides, just asking b/c I 
couldn't see it in your list.

Best
