Linking with libnosys generates a warning and a note from libc for each of the following functions: * _close_r * _fstat_r * _isatty_r * _lseek_r * _read_r The messages are: ``` in function `_close_r': closer.c:(.text._close_r+0xc): warning: _close is not implemented and will always fail note: the message above does not take linker garbage collection into account ``` Removing libnosys gets rid of these messages, and the compiler still generates the same output.
