Package: gcc-4.3
Version: 4.3.3-15
Severity: normal

Note: this is a bug concerning the c99 utility, but since c99 uses
gcc, I report the bug against gcc. Also note that both gcc-4.4 and
gcc-snapshot have the same problem. I've also reported the bug on
GCC's bugzilla: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40960

In http://www.opengroup.org/onlinepubs/9699919799/utilities/c99.html
POSIX specifies:

  -D  name[=value]
    Define name as if by a C-language #define directive. If no = value
    is given, a value of 1 shall be used. The -D option has lower
    precedence than the -U option. That is, if name is used in both a
    -U and a -D option, name shall be undefined regardless of the
    order of the options.

However, gcc doesn't take the precedence rule into account:

$ cat tst.c
int main(void)
#ifdef FOO
  return 1;
  return 0;
$ c99 tst.c -UFOO -DFOO=1
$ ./a.out
zsh: exit 1     ./a.out

whereas FOO should be undefined and the return value should be 0, not 1.
