* HB_ULONG -> HB_SIZE, where I could find out from warnings.
+ Added parameter names to some function declarations where they
were missing.
; Przemek, please check me. I feel I will mess this up if continuing
beyond this point, so I'd appreciate if you could take a look at
HB_ULONG to HB_SIZE conversion from an intrinsic perspective,
there seem to be places where it needs further tweaks to get us
full Win64 support. [ I've also intentionally left this area
more or less intact when doing the previous pass of conversion. ]
; There are places where simple 'int' is used, while it should be
HB_SIZE (or maybe size_t? in some places).
; Also, Win64 conversion will need some more work f.e. in filesys.c
where WinAPI file I/O functions can't accept a 64-bit value.
First I will report these and if they seem complicated I'll
revert to HB_SIZE = HB_ULONG for Win64 in the being.
