Sorry, I meant -ansi is the same as -std=c89:
From gcc(1):
c89
iso9899:1990
ISO C90 (same as -ansi).
And again, you missed what I said about declarations not at the top. This is
why we use -ansi -pedantic-errors:
[EMAIL PROTECTED] tmp]$ gcc -std=c99 foo.c
[EMAIL PROTECTED] tmp]$ gcc -std=c99 -pedantic-errors foo.c
[EMAIL PROTECTED] tmp]$ gcc -ansi -pedantic-errors foo.c
foo.c: In function 'main':
foo.c:9: error: ISO C90 forbids mixed declarations and code
[EMAIL PROTECTED] tmp]$
It's the ONLY combination that seems to catch that error.
