// Subject: overloaded function resolved incorrectly
// Date: Tue, 4 May 93 13:59:18 EDT
#include <stdio.h>
// Given the following overloaded function definitions
void ovf(unsigned long, short, short) { printf ("PASS\n"); }
void ovf( int, short, unsigned long) { printf ("FAIL\n"); }
// 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).

unsigned long pixmap = 0;
unsigned int x = 0;
unsigned int y = 0;

return 0;
