Subject: Fix a bug where the USB interrupt doesn't make it to the interrupt vector table.
X-Git-Url: https://git.zarvox.org/shortlog/month?a=commitdiff_plain;h=2a1ffd05809ec37c0d85241bdf685d046ed77caf;p=usbsnes.git

Fix a bug where the USB interrupt doesn't make it to the interrupt vector table.

Somehow, either due to version differences between v-usb or
avr-gcc/avr-libc, SIG_INTERRUPT0 was not getting linked to the interrupt
vector table where it belonged.  Naming the routine INT0_vect seems to
fix the problem.
