Per POSIX, unlinkat should be declared in <unistd.h>; but cygwin only declares it in <fcntl.h>:
$ echo '#include <unistd.h>' | gcc -E - | grep unlink int __attribute__((__cdecl__)) unlink (const char *__path ); $ echo '#include <fcntl.h>' | gcc -E - | grep unlink extern int unlinkat (int, const char *, int); Likewise, symlinkat should be in <unistd.h>; but cygwin only declares it in <stdio.h>: $ echo '#include <unistd.h>' | gcc -E - | grep 'symlink' int __attribute__((__cdecl__)) symlink (const char *__name1, const char *__name2); $ echo '#include <stdio.h>' | gcc -E - | grep 'symlink' int __attribute__((__cdecl__)) symlinkat (const char *, int, const char *); -- Eric Blake -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
