// Test fix for PR20366
//
// { dg-do compile { target *-*-aix* } }
// { dg-options "-D_LARGE_FILES" }
//
// cstdio includes stdio.h and undefs most of the functions declared
// therein, unfortunately this means that #define fopen fopen64 goes
// away. This tests the fix, and ensures that with -D_LARGE_FILES
// fopen et. al. are indeed aliased to the large file equivalents.
//
// There are many other #define foo foo64 in the AIX headers, but
// these all work out fine as they are not undefined in libstdc++.
// This list is probably incomplete:
//
// Symbol Return type Large file declaration.
