Okay.  Thanks for reporting.

My guess is that the Windows version could be simplified, too, if
we introduce a function to get the path to the binary.  On Linux
it should use "readlink /proc/$$/exe", on Darwin the function you
pointed to, on Win32 _pgmptr, as a fallback look for argv[0] in
$PATH if someone on another platform is interested.
