Does gcc -ansi work?

I don't have any solaris at hand to check, but IIRC "standard mode" is
enabled by having a global variable: int __xpg4=1; in your program (not
that you should do it yourself, the compiler should pass some appropriate
..o to the linker).

Having int __xpg4=1; in my source, it works:

$ fgrep xpg4 str.c
int __xpg4=1;
$ gcc -ansi str.c
$ LC_ALL=de_DE.UTF-8 ./a.out
strlen of buf with ascii char 16
[a ]
strlen of buf utf char 16
[� ]

$ gcc str.c
$ LC_ALL=de_DE.UTF-8 ./a.out
strlen of buf with ascii char 16
[a ]
strlen of buf utf char 16
[� ]

Using only -ansi does not work either
Thanks for the trick.
