Hi Oza,

You're running into a GNU extension to C89, and a standard part of C99.

$ gcc -pedantic -std=c99 -W -Wall -Wno-unused-variable c99.c

No error messages.

$ gcc -pedantic -std=c89 -W -Wall -Wno-unused-variable c99.c
c99.c: In function `main':
c99.c:11: warning: ISO C89 forbids mixed declarations and code

Error messages.

HTH,
--Eljay
