You didn't provide much information -- It would have been helpful
to know if the size increase was in the .text PSECT or .data.

My initial guess would be that the new compiler initializes
.data for global uninitialized data rather than using .bss.
At least, that's one difference between old and new VAX PCCs
(e.g. BSD's and System V's).  That certainly makes for larger
object files.
