I believe that OS_POSIX is basically defined as !OS_WIN. In that case, this
could be simplified to:

#if !defined(OS_LINUX)

... but the intent of the CL is more clear this way. This file lgtm

 // The following are glibc-specific
 
 size_t fread_wrapper(void *ptr, size_t size, size_t n, FILE *file) {
   return fread(ptr, size, n, file);
 }
 
 size_t fwrite_wrapper(const void *ptr, size_t size, size_t n, FILE *file) {
   return fwrite(ptr, size, n, file);
 }
