+// Subject: overloaded function resolved incorrectly
+// Date: Tue, 4 May 93 13:59:18 EDT
+
+#include <stdio.h>
+
+// Given the following overloaded function definitions
+
+int ovf(unsigned long, short,         short) { printf ("PASS\n"); return 0; }
+int ovf(          int, short, unsigned long) { printf ("FAIL\n"); return 1; }
+
+// and the call
+//
+//   ovf(unsigned long, unsigned int, unsigned int)
+//
+// it seems to me (and to cfront) that this should resolve to ovf #1 above,
+// but g++ resolves it to ovf #2.  Resolving to ovf #1 requires two conversions
+// (unsigned int => short) while resolving to ovf #2 takes two conversions
+// (unsigned long => int, unsigned int => short) and a promotion
+// (unsigned int => unsigned long).
+
+int main(int, char**)
+{
+    unsigned long pixmap = 0;
+    unsigned int x = 0;
+    unsigned int y = 0;
+
+    return ovf(pixmap, x, y);
+}
