This question referes to mingw compiler, a port of gcc for win32.

When I tryed yesterday to compile this code:

int test(void);

int main()
{
return 0;
}

int test()
{
for( int i = 0 ; i < 5 ; i++ );
return 0;
}

i got the following error: "something about C99 standard"
then I changet the code like that:
int i = 0;
for( i, ..)

and the error was gone.

It was strange. When I tryed to reproduce it with the latest compiler
from mingw I couldn't do it, so I'm asking if that was a bug or just a
misconfiguration.

In my large projects this is not happening. Maybe I should post it to
mingw newsgroup but it referes the C99 standard.

If anyone has encountered this kind of 'strange error' please let me
know.

Hi,

I assume the error you got was:
"error: `for' loop initial declaration used outside C99 mode"

You do not seem to have enabled the C99 mode here. Hence the error.

Enable the C99 mode, by using the compiler option "-std=c99".

Hope that helps.

Yes. That was the problem, and in my projects it didn't happened
because they had that compiler command. This can be reproduced only
outside the projects.
In individual files without that command, I discovered after some
digging.
Thanks for the answer.
