My previous tests were done by calling link_warning. When
suddenly stub_warning is used (that is, I link in libnosys.a), I
see double:
/tmp/cris/lib/gcc/cris-unknown-elf/4.0.0/../../../../cris-unknown-elf/lib/libc.a(closer.o):
In function `_close_r':
/home/hp/cvs_areas/combined/combined/newlib/libc/reent/closer.c:53: warning: warning: _close is not implemented and will always fail
...
So, the GNU linker already adds a "warning: ".
Unless the double warning is intended :-) I suggest this change:
2005-01-21 Hans-Peter Nilsson <hp@axis.com>
* libnosys/warning.h (stub_warning): Remove "warning: " prefix.
Index: warning.h
