[Issues] LDAC broken on AMD64

[Jan Snigula]

Hi all,

the default build of LDAC seems to be broken on 64 bit linux  
installations. This explains the preastrom fails mail I sent  
recently. By default LDAC is compiled without an INT64 define. This  
causes e.g. ldacconv to mess up the conversion of floats in the  
header (astrometry, airmass etc.). Adding a -DINT64 under lib/Linux/ 
Makefile. A more permanent solution would probably be to create a  
different configuration for 64bit Linux implementations.

Cheers,

Jan
