[GenABEL-dev] bug_in_OmicABEL_reshuffle_fixed

[Содбо Шарапов]

Dear all!
I fixed bug in OmicABEL_reshuffle.
This bug was only for big data. The reason is, that for big output data
value of tile_coordinate is higher, than max(int).
For example: for data with 1080 ids and 122756 SNPs
max(tile_coordinate)=1080(ids) * 122756(SNPs) * 8 (sizeof(double)) * 5
(columns:beta_1,se_1,beta_SNP,se_SNP, etc) =  5 303 059 200
max(int) = 2 147 483 647
max(unsigned int) = 4 294 967 295
This values is lower than max(tile_coordinate). That's why tile_coordinates
for a half of data were incorrect and senseless.
So, the solution of this problem is change type of variabels for
tile_coordinates: I select int64_t instead of int.
max (int64_t)= 9,223,372,036,854,775,808. I think this is enough!=)
Now, "reshuffle" works with big data correctly. Compilation for Linux and
Windows was succesful.
