[Bug c/26494] New: -pedantic-errors can be overridden by -W*

["fn_x at hotmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

This simple incorrect program:

int main() { puts("Hello"); }

when compiled with gcc -std=c99 -pedantic-errors is rejected with

test.c: In function ?main?:
test.c:1: error: implicit declaration of function ?puts?

However, add -Wall to the options, and it becomes:

test.c: In function ?main?:
test.c:1: warning: implicit declaration of function ?puts?

and the program compiles and runs without errors. I think gcc should not
compile it. Also, reordering the options doesn't change anything.

Given how old this is (I can see it with gcc 3.3.6, 3.4.5, 4.0.2 and
4.1(20060223)), I'm a bit surprised if it hasn't come up before, but I searched
bugzilla and didn't find anything. Sorry for anything I missed.
