Fix WINT_TYPE for FreeBSD (was: stdint.h type information needed)

After my patch for stdint.h support on FreeBSD has gone in, we are
nearly fine on that front.  Nearly, because as we see from

gcc.dg/c99-stdint-1.c and gcc.dg/c99-stdint-7.c still fail with

  .../gcc/testsuite/gcc.dg/c99-stdint-1.c: In function 'test_misc_limits':
  .../gcc/testsuite/gcc.dg/c99-stdint-1.c:219: error: size of array 'a'is negative


  .../gcc/testsuite/gcc.dg/c99-stdint-7.c:213: error: #error "WINT_MIN not usable in #if or wrong value"
  .../gcc/testsuite/gcc.dg/c99-stdint-7.c:216: error: #error "WINT_MAX not usable in #if or wrong value"

Both of these relate to WINT_MIN and WINT_MAX, and indeed we have

  WINT_MIN = -2147483648, __WINT_MIN__ = 0
  WINT_MAX =  2147483647, __WINT_MAX__ = 4294967295

The patch below fixes this and resolves the following testcases without
any other regressions on i386-unknown-freebsd7.1:

  < FAIL: gcc.dg/c99-stdint-1.c (test for excess errors)
  < FAIL: gcc.dg/c99-stdint-7.c (test for excess errors)
  < FAIL: gcc.dg/wint_t-1.c (test for excess errors)

Okay for trunk?  Should this also be applied to open release branches?
