compiling - gcc vs. c89
• Use gcc if:
• you’re porting an open-source application
• you want to write portable code that will run on
other platforms
• support contracts available from
http://www.gccsupport.com
• Use HP c89 if:
• you’re calling many MPE intrinsics
– #pragma instrinsic
• you need long pointer support
• you want to use an HP-supported compiler
