Gnulib module: link
Portability problems fixed by Gnulib:
@itemize
@item
This function is missing on some platforms:
mingw, MSVC 14.
@item
This function fails to reject trailing slashes on non-directories on
some platforms:
FreeBSD 7.2, Solaris 11.3, Cygwin 1.5.x.
@item
When the second argument is a dangling symlink, some platforms follow
that link and create the destination rather than failing:
IRIX 6.5.
@end itemize
Portability problems not fixed by Gnulib:
@itemize
@item
When the first argument is a symlink, some platforms create a
hard-link to what the symlink referenced, rather than to the symlink
itself. Use @samp{linkat} to force a particular behavior.
@end itemize
