[Clas_offline] libfpack.a, libfputil.a, and libmapmanager.a for 64-bit compilation

[Maurik Holtrop]

Dear Krishna,

I have actually tried a few times to make gsim run in 64 bit mode. The problem for me has never been compiling or linking the code, the problem has always been that the output produced was not consistent with the output produced for 32-bit gsim. I must admit that this was quite some time ago, before there were more official versions of 64-bit CERNLIBS, and that I have completely given up on this effort. For me, I only trust the 32-bit version of CERNLIB. Still, I would strongly suggest that when you have the code compiled and linked, you make sure that your 64-bit version and 32-bit version give identical answers.  Make sure the test run contains significant enough statistics and your tests are sufficiently picky to make sure you catch oddities. 

If you (or anyone else) do get a 64 bit version working, please let everyone know exactly what you did to get it going and what you did to verify your version!

Best,
	Maurik
