+;;; Large file support for Solaris. Define some of the 64-bit types
+;;; we need. Unlike unix-glibc's large file support, Solaris's
+;;; version is a little simpler because all of the 64-bit versions of
+;;; the functions actually exist as functions. So instead of calling
+;;; the 32-bit versions of the functions, we call the 64-bit versions.
+;;;
+;;; These functions are: creat64, open64, truncate64, ftruncate64,
+;;; stat64, lstat64, fstat64, readdir64.
+;;;
+;;; There are also some new structures for large file support:
+;;; dirent64, stat64.
+;;;
+;;; FIXME: We should abstract this better, but I (rtoy) don't have any
+;;; other system to test this out on, so it's a Solaris hack for now.
