Compiling the following code in test.cpp:
#include <limits.h>
#include <stdlib.h>
int main ( void )
{
realpath ( "//.", NULL );
return 0;
}
This works:
% g++ test.cpp
This doesn't:
% g++ -std=c++11 test.cpp
test.cpp: In function ‘int main()’:
test.cpp:8:25: error: ‘realpath’ was not declared in this scope
realpath ( "//.", NULL );
^
Is this expected behavior?

I don't have a Cygwin machine at hand, but try compiling with
-std=gnu++11 instead of -std=c++11. realpath() might be hidden if
__STRICT_ANSI__ is defined (when you use -std=c++11, IIRC).
