+ * Cygwin to distinguish between a directory and an executable with
+ * the same name excluding the ".exe" extension. For example, the
+ * Cygwin Python build directory has a "Python" directory and a
+ * "python.exe" executable. This causes isxfile() to erroneously
+ * return false. If isdir() returns true and there is enough space
+ * to append the ".exe" extension, then we try again with the
+ * extension appended.
