Subject: Fixed a small bug in the ISR code where it was looking for the gpio program.
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?a=commitdiff_plain;h=0150b024789f6b7356a738334d3b325a50297452;p=wiringPi.git

Fixed a small bug in the ISR code where it was looking for the gpio program.
Should now work correctly on Arch, or other systems that install gpio as
/usr/bin/gpio.
