tools: Prevent compiler warnings regarding unused argument and printf

* tools/if_mach.c (main): Remove unused "envp" argument.
* tools/if_not_there.c (main): Likewise.
* tools/if_mach.c: Expand tabs to spaces.
* tools/if_not_there.c: Likewise.
* tools/setjmp_t.c (getpagesize): Define for Win32; include windows.h.
* tools/setjmp_t.c (main): Make printf() format specifier string
non-empty (to suppress compiler warning).
* tools/setjmp_t.c (main): Adjust printf() format specifier for WORDSZ
value (unsigned long instead of int).
