OK, I could see that.  But see more below.

Only to get the "standard" (such as they are) typedef set, so that 
porting is easier.  They are of no use on their own.

THAT I must agree with.  It is an excellent reason *not* to use them, 
since I know for a fact that perl, inter alia, tests them to determine 
large file support.  At the least, we should probably not use them 
until or unless we manage to have "real" large-file support.

I will just let that sleeping dog lie, and use the current offset_t 
definition.

Thanks for the info and advice.
