The warning is easy to silence, the bigger problem
is that this function will modify HVM string directly,
which may cause HVM corruption.
It needs to be rewritten to work on a copy of the
string.
We have the exact same kind of problems waiting to be
fixed in examples/gfspell.

This is an old C function but it's used in a 3rd party lib so I can't
use HB's standard one.
When I build it with 2.0.0beta3 gcc warnings. How can I fix it?
#include <extend.h>
#ifdef __HARBOUR__
HB_FUNC( BIT )
#else
CLIPPER bit( void )
#endif
{
char *ptr;
unsigned char mask;
unsigned int loc,
offset = _parni( 2 ) - 1,

loc = offset / 8;
if ( loc < _parclen( 1 ) )
{
ptr = _parc( 1 ) + loc; <---- warning here
loc = offset % 8;
res = *ptr << loc & 0x80;
if ( PCOUNT > 2 )
{
mask = (unsigned char ) 0x80 >> loc;
if ( _parl( 3 ) )
*ptr = *ptr | mask;
else
*ptr = *ptr & ~mask;
}
}
_retl( res );
}
