This is not valid C code for at least several reasons:

1) main must return int.  void is not acceptable.
2) main must take either void parameters or an int and a char **.
   an undefined param list is not acceptable.
3) 'int i' is not valid in the declaration portion of a for loop.
   this is valid c++ code, but not valid c.

The compiler is well within its rights to reject your program
for any of these three reasons, but gcc only rejects because of #3:

test.c: In function `main':
test.c:3: syntax error before `int'
test.c:3: `i' undeclared (first use this function)
test.c:3: (Each undeclared identifier is reported only once
test.c:3: for each function it appears in.)
test.c:3: syntax error before `)'

Odd -- it compiled for me.  Could you elaborate *specifically* as to the
error messages you got?
