Subject: Ruby on LLP64

Hi,

I am interested in embedding ruby on some physics simulation code. My 
application is numerically intensive and it is important to me that the code 
can be compiled with 64-bit windows in native 64 bit mode (at least soon in 
future). I searched on the internet, but so far I cannot find much on this 
issue except that the ruby official page says that it works only in win32 
mode.
The source of my concern is that Win64 is based on LLP64, where sizeof(long) 
is 4, while sizeof(void*) is 8. Here and there I find statements that say 
size of long and void* has to be the same for ruby to run correctly because 
of the way VALUE is used, but I just do not know how serious this constraint 
is. For example, just defining

#define VALUE long long

will solve the problem or are there more fundamental problems regarding this 
issue?

Thanks,
aquamm
