make on Linux Mint Debian v7 returns an error

[brian-in-crawford]

As per subject, I'm running Linux Mint Debian Edition v7. I ran a 'git pull' at roughly 9:30am on March 13th, and this was the output when I ran make

brian@ryzen:~/sourcedists/git/cbm-basic$ git pull Already up to date. brian@ryzen:~/sourcedists/git/cbm-basic$ make cc -Wall -std=c99 -O2 -o basic basic.c -lm basic.c: In function ‘do_sleep_ticks’: basic.c:1268:9: error: implicit declaration of function ‘usleep’; did you mean ‘sleep’? [-Wimplicit-function-declaration] 1268 | usleep((unsigned int)usec); | ^~~~~~ | sleep make: *** [Makefile:27: basic] Error 1

Try make clean before make?
