Description of problem:

I just tried to compile package kdemultimedia-3.1.4-1 from Redhat
Fedora Core 1.

The compiler said

1.

resample.c:1288: warning: operation on `dest' may be undefined
resample.c:1289: warning: operation on `dest' may be undefined

The offending source code is

  *dest++ = *(dest - 1) / 2;
  *dest++ = *(dest - 1) / 2;

This code is undefined. Suggest

  *dest = *(dest - 1) / 2;
  ++dest;
  *dest = *(dest - 1) / 2;
  ++dest;

2.

wm_helpers.c:175: warning: comparisons like X<=Y<=Z do not have their
mathematical meaning

The offending source code is

        if( WM_MSG_LEVEL_NONE <= level <= WM_MSG_LEVEL_DEBUG )

Maybe 

        if ((WM_MSG_LEVEL_NONE <= level) 
			&& (level <= WM_MSG_LEVEL_DEBUG))

was what the programmer meant ?

3.

cdtext.c:402: warning: this function may return with or without a value

The offending source code is

int wm_get_cdtext(struct wm_drive *d)
{
  /* alloc cdtext_info */

  unsigned char *buffer;
  int buffer_length;
  int ret;
  int i;
  struct cdtext_pack_data_header *pack, *pack_previous;
  cdtext_string *p_componente;
  struct cdtext_info_block *lp_block;
  if(d->get_drive_status == NULL)
    return;

Suggest add expression to return statement.
