* make_vc.mak
* contrib/mtpl_vc.mak
+ -w34701 VC flag added to enabled warning 4701 (uninitialized vars) on -W3 level.
% -FD VC flag removed. This is only needed for IDEs.
% -Gs VC flag moved to the common section.
% VC flags synced in contrib with core.
+ TOFIX added for WinCE command line. It's full of stuff which is _probably_ not needed.
+ NOTE added about MSDN page explaining VC switches.
; NOTE: -W4 and -Wp64 are recommended for MSVC.
; TOFIX: There are still a few uninit vars warnings:
harboury.c(7226) : warning C4701: potentially uninitialized local variable 'hb_complval' used
macroy.c(3095) : warning C4701: potentially uninitialized local variable 'hb_macrolval' used
dbffpt1.c(2671) : warning C4701: potentially uninitialized local variable 'ulType' used
dbffpt1.c(2614) : warning C4701: potentially uninitialized local variable 'ulSize' used
dbffpt1.c(3073) : warning C4701: potentially uninitialized local variable 'ulOldSize' used
dbffpt1.c(3083) : warning C4701: potentially uninitialized local variable 'ulBlock' used
dbffpt1.c(3652) : warning C4701: potentially uninitialized local variable 'pBlock' used
