#13 nmonmerge2 doesn´t compile on debian 9.11

[Joerg Esser]

Under Debian 9.11 I get this error
gcc -o nmonmerge -O3 nmonmerge2.c
nmonmerge2.c: In function ‘main’:
nmonmerge2.c:60:21: warning: implicit declaration of function ‘getopt’ [-Wimplicit-function-declaration]
while ( -1 != (i = getopt(argc, argv, "?hva" ))) {

^~~~~~~
nmonmerge2.c:166:2: warning: implicit declaration of function ‘unlink’ [-Wimplicit-function-declaration]
unlink(TEMPFILE);

I added #include <unistd.h> to the file to resolve the error.
Patch in attachment. </unistd.h>

This is just a hack. Dont know the correct way.

Thx for the fish ;)
