The signature of wiringPiSetupGpioDevice changed in f3415b5, but this example's code was not changed to reflect this which causes it to fail to compile on the master branch. Looking through the source code of that commit, I believe this change should restore the pre-change behavior for this example.

jwlodek@raspberrypi:/epics/utils/WiringPi/examples $ make speed
[CC] speed.c
speed.c: In function ‘main’:
speed.c:96:3: error: too few arguments to function ‘wiringPiSetupGpioDevice’
   wiringPiSetupGpioDevice () ;
   ^~~~~~~~~~~~~~~~~~~~~~~
In file included from speed.c:26:
/usr/local/include/wiringPi.h:228:13: note: declared here
 extern int  wiringPiSetupGpioDevice(enum WPIPinType pinType); //Interface V3.3
             ^~~~~~~~~~~~~~~~~~~~~~~
make: *** [Makefile:158: speed.o] Error 1

I suggest creating a CI workflow for testing example compilation in addition to the project build test.
