One other thing I just now noticed -- the Windows substitute for unistd.h may need something like this: #define STDIN_FILENO 0 #define STDOUT_FILENO 1 #define STDERR_FILENO 2 if Windows doesn't already have the equivalent. The backtrace code uses STDERR_FILENO rather than fileno (stderr) as it's better not to rely on stdio's data structures after an assertion has failed.
