Building on Slackware 15,0-beta
  gcc 10.3
  gtk 2.2.24

The strncpy construct in adif3.c (by line 527) fails due to "assining src to itself". I tried 2.0.21 and the related section complained of a null destination record.

The workaround uses the algorithm for strncpy.

The code is (j added as a gint)

 qfield = q[fld];
  space_ptr = q[fld];
  space_ptr = strpbrk (space_ptr, " ");
  qfield_len = space_ptr - qfield;         // length of string from start to space

  if (qfield_len == 0) {                   // if no space, then the field is either null or somehow malformed
qfield = q[fld];
  } else {
for (j = 0; j < qfield_len && qfield[j] != '\0'; j++)
    qfield[j] = qfield[j];
                        for ( ; j < qfield_len; j++)
                    qfield[j] = '\0';
// strncpy (qfield, q[fld], qfield_len);  // Save the string from start to space, not including the space.
qfield[qfield_len] = '\0';             // Null terminate the desired string

This gives a successful build.
