64-bit porting issue on cmsSetUserFormatters

Hi,

I've once asked about the usage of cmsSetUserFormatters
function to pass the
user defined parameters to cmsFORMATTER functions.
And the answer was to use dwInput/dwOutput for passing
pointers. And it
works pretty well on 32-bit codes but I'm now porting the
code to 64-bit
environments including Windows and Linux. And I found that
LLP64
environments like Windows (unsigned long == 32bit), DWORD is
not enough to
carry pointers. So are there any plan to switch these
parameters to 64-bit
variables? I'm currently modifying the header to support
64-bit parameters.

Thanks in advance,

A year or more ago Marti promised me that a future lcms
release would 
elminate use of these Windows-derived typedefs.  There
were/are 
causing lcms not to compile under MinGW/GCC.  It seems that
Windows 
itself is now sufficient incentive to use portable typedefs
(e.g. from 
ANSI C) rather than the Windows derived ones.
