Migration from HPUX to REL5
We have our source codes migrated from HP-UX to LINUX REL 5.
In some of the scripts, certain flags like -DHPUX -DUNIX have been use.
I wanted to know, what can replace these flags in LINUX?
then certain optimization flags are also used like +O2, etc. these give an error as O2:command not found in Linux.
What can be the proper replacement for them?
