20030610: 20030609: GEMPAK 5.6J build fails on RH 8.0

Robert,

It sounds like the process of -O2 uses a lot of resources when compiling
which ran you out of resources for that routine. Its possible that you could 
compile the rest of GEMPAK with -O2, but I have seen problems with OSF/1
where input pointer and output pointer was the same variable, and high
levels of optimization collapse those argument lists.

Glad you have now moved on though,

Steve
