Fix memory trashing bug.

This occurred because a global with structure type was declared without the structure definition in scope. ORCA/C allows this, and just treats the struct variable as having size 0. As a result, it effectively shares the storage of whatever comes after it in the OMF file, leading to memory trashing.
