// 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.
