Add proper casts to avoid signed vs. unsigned mismatches in strmake().

Once at it, could you please explain to me what the hell is going on here (min)? I came across this function recently, and do not agree with its logic. I would write it like
char *strmake(const char *fmt, ...) { int n; size_t size = 100; char *p = xmalloc (size+1); va_list ap;
va_start (ap, fmt); n = vsnprintf (p, size, fmt, ap); while (n < 0) { size *= 2; p = xrealloc (p, size+1); n = vsnprintf (p, size, fmt, ap); } if ((size_t)n == size) p[size]=0; va_end (ap); return p; }
By the way, either Wine's snprintf implementation is wrong or I do not know how to use it correctly. I am submitting a conformance test...
