* contrib/hbct/fcopy.prg
     ! Fixed crash in FILECOPY() (reported by Mario H. Sabado)
       [TOMERGE RC1 - if correct]

   * contrib/hbodbc/odbc.c
     * Using sizeof() wherever possible.
     ! SQLGETDATA(): One strcpy() converted to hb_strncpy()
     + SQLGETDATA(): One TOFIX added for strcat() usage and 
                     possible buffer overrun.
                     Also, it looks to me that both of the above 
                     would better be replaced by memcpy() calls 
                     otherwise it cannot support embedded '\0's.
                     Anyone?

* Harbour Project source code:
* CT3 file functions:
* FILECOPY(), FILECOPEN(), FILECCLOSE(), FILEAPPEND()
*
* Program..: fcopy.prg
* Author...: Frederic J. Bell
* Dated....: Jun,17 94
* Revised..: Sep,20 94
* Purpose..: Replaces the following ca-tools functions which generate GPF's
* FileCopy(), FileCOpen() & FileAppend()!
* Relies on: Clipper (can you believe it!)
* Compile..: /n /m /w /[/p /b /l] /es2
* Notes....:
* No copyright - released into the public domain NSA.
*
* Copyright 2007 Przemyslaw Czerpak <druzus / at / priv.onet.pl>
*
* added FILECDATI() and rewritten above functions for CT3 compatibility
* and some problems fixing,
