This is the basically the situation with 64bit IO for Solaris as well. I
have have working on it during the last couple of weeks and it has ended
requiring more changes than expected due to conflicts with ib_stdio.

Classic engine is reading/writing big db ok from isql, gstat/gfix ok,
gbak can generate a backup file > 2Gb ok but restoring a database fails
at the 2Gb point. This is odd because the open/write procedures it uses
on the database are the same pio routines used by isql which operate on
a >2Gb database with out problem. Trussing gbak shows it using
opening/creating the new database with the 64bit version of open, any
suggestions very welcome. 

Super engine seems ok for everything - it uses pread/pwrite which needed
changing - but as I don't use super it has had only basic testing.

My current plan is to build clean 32bit only versions for the release
files and a 64bit super as a snapshot build with the differences as a
patch within the cvs.
