Hi Luc, Heinrich,


Note that I get this on gnu.emacs.bug, and I haven't seen the original
message so I may be missing something.

In general that's correct behaviour, as C requires its input to be a
vaild text file and in valid text files all lines must have a trailing
line terminator.  Some compilers *will* actually ignore the last line,
if it doesn't have a line terminator.

Same goes for other types of text files.  The behaviour of standard C
functions like fgets() is not well defined on text files that are not
valid with regard to this.  Therefore some programs will fail in this
case.

Was there a reason to want to have invalid C source originally, or was
that just an aesthetic problem?


so long, benny
