 /*
  * open.c
  *
- * The open syscall is weird, because it's defined as a varadic
- * function, but implementing it as such generally sucks for
- * performance.  Thus we generate it as a 3-argument function,
- * but with explicit __cdecl assuming the __cdecl convention is
- * independent of being varadic.
+ * On 32-bit platforms we need to pass O_LARGEFILE to the open()
+ * system call, to indicate that we're 64-bit safe.
