[fpc-pascal] Binary compatibility between Intel CPU and PowerPC CPU

Well, the (inefficient / multiplatform - choose one) way is to not store 
data as binary, instead using something like XML.  Probably not an 
option, but there will be a tradeoff and a penalty no matter what.  One 
way would be store the data in the endianness of the consistently slower 
platform (so as not to further slow down a system that is already 
slow).  Another would be to pick the endianness of the most popular 
platform for your product so that it performs as well as possible where 
the most users are.  Its a decision you'll have to make on your own, though.

I haven't smoked for 2 years, 4 weeks and 2 days, saving $3,427.14 and 
not smoking 22,847.63 cigarettes.
