OK Stuart, I make it a good practice to give each header file a unique
name using #define, the reason being that if 2 modules need to use the
same header file they'll get tangled up at link time.  So:

#ifndef GETSAFE_LIB
#define GETSAFE_LIB

char *getsafe(char *buffer, int count);

#endif

In my opinion would be better
