// Test fix for PR20366

// { dg-do compile  { target *-*-aix* } }

// { dg-options "-D_LARGE_FILES" }

//
6
// cstdio includes stdio.h and undefs most of the functions declared
7
// therein, unfortunately this means that #define fopen fopen64 goes
8
// away. This tests the fix, and ensures that with -D_LARGE_FILES
9
// fopen et. al. are indeed aliased to the large file equivalents.
10
//
11
// There are many other #define foo foo64 in the AIX headers, but
12
// these all work out fine as they are not undefined in libstdc++.
13
// This list is probably incomplete:
14
//
15
// Symbol          Return type     Large file declaration.
