[avr-gcc-list] Options on avr-gcc

[Javier Almansa Sobrino]

Hi everybody. Let's see if you can help me....

I've been compiling a proyect based on a AT90USB1287 and I've something
like this:

uint16_t n;

for (n = 0; n < 1000; n++); /* Delay loop */
 --- rest of code --

originally, this piece of code generates a delay loop, but I've changed
the AVR-GCC options on my Makefile and now, if I want the delay loop
works correctly, I must declare n as volatile. 

Any one knows what option I must to pass to AVR-GCC when compile to
avoid this. I don't remember and I've lost the original Makefile.

Thanks in advance.
