Compilation warning

[Mirraz]

Building dev86-0.16.20 by gcc-4.8.2 I'v got this compilation warning:
dbprintf.c:110:13: warning: incompatible implicit declaration of built-in function ‘strlen’ [enabled by default]

Yeah, there's a lot of compilation warnings with newer toolchains. I'm not going to just shoot this particular one, but I'd gladly accept patches to deal with the warnings.

If nobody is already working on it I will be happy to contribute on this issue. Please assign it to me.

As said in #15, I suggest you to contribute rather to Jody Bruchon's fork.

These headers would need to be added to bcc/dbprintf.c:

#include <string.h>
#include <unistd.h>

This was fixed in my fork in April 2015: https://github.com/jbruchon/dev86/commit/4ed1997c5f80728fdc1f4d55238d1cd5eef46c48
