Researching crash in bug 637

[Mehmet YASAR]

Hi,

I've a small patch that allows me to get "Font Explorer Light" go
further, both app are relying on a Windows bug.

For example take the following code (see the log) :

int main(int argc, char* argv[])
{
int i;
char buffer[20];

buffer[0] = buffer[1] = buffer[2] = 77;
i = GetLocaleInfoA(0x409, LOCALE_IFIRSTDAYOFWEEK, buffer, 1);

printf("%d:%d ret=%d\n", buffer[0], buffer[1], i);
return 0;
}

On Win2K we have <54:77 ret=0>
On Wine I have   <0 :77 ret=1>

We see that MS returns 0 as failure but modifies buffer[0] !
The following patch should fix this.

Mehmet
