Thanks! It builds fine here under debian x86 and debian MinGW32+Wine,
including 'make check'.

One nit, under MinGW32+Wine the 'benchmark' self test doesn't print
useful timings. That isn't important, but just in case you hadn't
noticed this and happen to know of a trivial patch to solve it, that
would be great.

MD5 27855594513760256ms 27855594513760256ms 4978691729784832ms

...

As far as I recall, earlier version used to say '0ms' instead, but I may
be mistaken. The difference may be because of wine changes too.
Anyway, not a big deal.

Well, I fixed the timing code and they give proper results on XP. Thus
I conclude that this is a Wine problem. Find below the relevant code.

static void
start_timer (void)
{
#ifdef _WIN32
GetProcessTimes (GetCurrentProcess (),
&started_at.creation_time, &started_at.exit_time,
&started_at.kernel_time, &started_at.user_time);
stopped_at = started_at;
#else
struct tms tmp;

times (&tmp);
started_at = stopped_at = tmp.tms_utime;
#endif
}

static void
stop_timer (void)
{
#ifdef _WIN32

&stopped_at.creation_time, &stopped_at.exit_time,
&stopped_at.kernel_time, &stopped_at.user_time);
#else

stopped_at = tmp.tms_utime;
#endif
}

static const char *
elapsed_time (void)
{
static char buf[50];
#if _WIN32
unsigned long long t1, t2, t;

t1 = (((unsigned long long)started_at.kernel_time.dwHighDateTime << 32)

t1 += (((unsigned long long)started_at.user_time.dwHighDateTime << 32)

t2 = (((unsigned long long)stopped_at.kernel_time.dwHighDateTime << 32)

t2 += (((unsigned long long)stopped_at.user_time.dwHighDateTime << 32)
+ stopped_at.user_time.dwLowDateTime);
t = (t2 - t1)/10000;
snprintf (buf, sizeof buf, "%5lums", (unsigned long)t );
#else
snprintf (buf, sizeof buf, "%5.0fms",
(((double) (stopped_at - started_at))/CLOCKS_PER_SEC)*10000000);
#endif
return buf;
