------- Comment #4 from manu at gcc dot gnu dot org 2009-10-15 15:21 -------
BTW, Clang claims to get this right. Quoting from:
http://clang.llvm.org/diagnostics.html
$ gcc-4.2 t.c
t.c:3: error: expected '=', ',', ';', 'asm' or '__attribute__' before '*'
token
$ clang t.c
t.c:3:1: error: unknown type name 'foo_t'
foo_t *P = 0;
^
This shows an example of much better error recovery. The message coming out of
GCC is completely useless for diagnosing the problem, Clang tries much harder
and produces a much more useful diagnosis of the problem.
