* src/rtl/hbsocket.c
* removed not longer valid TODO note
* contrib/hbmisc/bbabble.c
! fixed buffer size calculation (it fixes buffer overflow for small
strings, i.e. 2 bytes and does not allocate more memory then necessary
for long ones)
* contrib/hbct/dattime2.c
! fixed CToMonth() and CToDoW() to respect case intensive search for
strings with national characters
* variable name synced with Viktor branch
* contrib/hbct/strswap.c
! fixed NULL reference when neither 1-st nor 2-nd parameter is passed
by reference
* contrib/hbct/fcopy.prg
! fixed source file positioning in case of partial write
! use hb_FGetDateTime() / hb_FSetDateTime() instead of
FileDate()+FileTime() / SetFDaTi()
It's faster and unlike FileDate() and FileTime() it does
not leave directory open.
! fixed typo (RTE)
% minor simplification
* src/rtl/disksphb.c
! use dynamic binding for GetDiskFreeSpaceEx() function
; modifications below comes from Viktor fork:
* contrib/hbct/ctwin.c
% removed unnecessary declaration
* contrib/hbct/envparam.c
! do not call FreeEnvironmentStrings() is it's not necessary
* contrib/hbodbc/odbc.c
! fixed potential buffer overflow in SQLERROR()/SQLGETDIAGREC()
* contrib/hbnetio/netiosrv.c
! fixed possible NULL reference
* contrib/hbct/ctnet.c
! added missing check for result of WinAPI function call
* contrib/hbct/cttime.prg
! SecToTime(): fixed regression from 2007-11-18 13:46 UTC+0100
* contrib/hbwin/hbolesrv.c
! fixed char -> TCHAR after recent unicodification
