It sounds like you may be running into trouble because C++ requires
overloading for certain functions.  For example, in C, strchr is

char* strrchr(const char *, int);

while in C++ there are two:

const char* strrchr(const char *, int);
char* strrchr(char *, int);

So, if your OS provides only a C version of strchr, you still have
work to do to get the C++ versions right.
