#7 does not install

OS: Kubuntu 8.10 Intrepid
Compile runs fine, but make gives some errors:

dgtnixTest.cpp: In function ‘int main(int, char**)’:
dgtnixTest.cpp:45: error: ‘exit’ was not declared in this scope
dgtnixTest.cpp:68: error: ‘exit’ was not declared in this scope
make[2]: *** [dgtnixTest-dgtnixTest.o] Error 1
make[2]: Leaving directory `/home/adi/2/dgtnix-1.9.1/utils'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/home/adi/2/dgtnix-1.9.1'

Edit the files (dgtnix-1.9.1/src/dgtnix.c AND dgtnix-1.9.1/utils/dgtnixTest.cpp) by adding the following to top below other includes:

#include <stdlib.h>

The errors will disappear.
