Some more info. See the man pages:

lfcompile
largefile

The lfcompile page notes that if you pass the following flag to the
compiler your application will get compiled to support large files,
files greater then 2GB (2^31):

        -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64

I removed the 'O_LARGEFILE' flag from the open() system call
and then compiled using both /opt/SUNWspro/bin/cc and 
/usr/local/bin/gcc with the above flag. The program could then
create a file greater then 2^31 (2GB). This way you do not
need to modify your code.
