[Bug other/34979] Atomic line output requested in gcc

[jsm28 at gcc dot gnu dot org]

------- Comment #2 from jsm28 at gcc dot gnu dot org  2009-03-30 00:02 -------
cpplib does now use GCC's diagnostic.c, so if there is a bug here any more it
is not a preprocessor one.  It looks like diagnostic.c (in turn using
pretty-print.c) will write the diagnostic in one fputs call, then the final
newline in an fputc call, then flush the stream, so it's not yet using the
minimal number of stdio calls - though even with the minimal number of such
calls that doesn't and can't guarantee that multiple write() calls aren't used
underneath by libc.
