Hi, Eric
The file I changed is under platform/unix folder, so it is
only unix related.
Return type of open64 is int, it is of the same type as
m_nFD.
I have compiled and tested with a 2G file, open64 could open
it while open report an error.

[For future reference: this should have been submitted to
common-dev rather
than datatype-dev. Note that the file you are changing
is in /cvsroot/common, so that means it comes from the
common project. So therefore the proper mailing list
is common-dev. Don't worry about re-submitting this
CR - this is just for CR's in the future...]
Is open64() supported on all systems that open() is? Are
there any semantic differences in how you have to
treat the file handle m_nFD if you open it with open64().
rather than open()?
