! strcpy() -> hb_strncpy()
! strcat() -> hb_strncat()
; TOFIX1: There are still two strcpy()s left in SQL_SPRINTF().
Xavi, could you pls take a look at it?

! Fixed wrong buffer sizes (or no buffer limits) in some
string copy operations (potential buffer overruns).
* contrib/hbnf/getenvrn.c
! Fixed bad leak in FT_GETE() on Win32 systems.
* source/rtl/fstemp.c
! hb_fsTempName(): Fixed potential buffer overrun by one byte.
* Minor formatting.
* source/rtl/fstemp.c
* source/rtl/hbffind.c
* contrib/xhb/hboutdbg.c
* Using sizeof() instead of explicit size in string copy operations.
; TODO: There is a lot more to fix like this.
; Przemek, could you double check these changes pls?
I can send you the .diff if it helps.
