snprintf.c on win32 does not compile..

.... there is no sys/ioctl.h. Trivial patch below:

diff -c -r1.6 snprintf.c
*** snprintf.c  22 Feb 2005 04:57:24 -0000      1.6
--- snprintf.c  27 Feb 2005 17:05:54 -0000

*** 40,46 ****
--- 40,48 ----
  Your platform must have a thread-safe snprintf() to compile with
threads.
