Yes, this is the interesting bit of code. Note what the documentation says:

   AVAILABILITY
      These  functions  are  available  when  _POSIX_THREAD_SAFE_FUNCTIONS is
      defined.

So our code is doing what the documenation says it should do. Interestingly, 
this code seems to work on MiNGW when in log.c but not when in file.h (its new 
location). That's why I'd like to look throgh MinGW's headers.
