[Bug 1166105] [NEW] incorrect error message ('-Werror=edantic') with -pedantic

[James Hunt]

Public bug reported:

Specifying '-pedantic' and '-Werror' together with a file that triggers
a pedantic warning results in an incorrect message:

$ gcc -Werror foo.c
foo.c: In function ‘main’:
foo.c:21:5: erreur: ‘for’ loop initial declarations are only allowed in C99 mode
foo.c:21:5: note: use option -std=c99 or -std=gnu99 to compile your code
$ gcc -pedantic -Werror foo.c
foo.c:14:6: erreur: ISO C90 doesn’t support unnamed structs/unions [-Werror=edantic]
foo.c: In function ‘main’:
foo.c:21:5: erreur: ‘for’ loop initial declarations are only allowed in C99 mode
foo.c:21:5: note: use option -std=c99 or -std=gnu99 to compile your code
cc1: all warnings being treated as errors
$ gcc -Werror -pedantic foo.c
foo.c:14:6: erreur: ISO C90 doesn’t support unnamed structs/unions [-Werror=edantic]
foo.c: In function ‘main’:
foo.c:21:5: erreur: ‘for’ loop initial declarations are only allowed in C99 mode
foo.c:21:5: note: use option -std=c99 or -std=gnu99 to compile your code
cc1: all warnings being treated as errors

Note that '-Werror=edantic' is truncated. Presumably, it should be
showing '-Werror=pedantic'?

Note however that both '-Werror=edantic' and '-Werror=pedantic' are
(currently) invalid gcc options.
