File offset to the indirect symbol table.

The sections that contain "symbol pointers" and "routine stubs" have indexes and (implied counts based on the size of the section and fixed size of the entry) into the "indirect symbol" table for each pointer and stub. For every section of these two types the index into the indirect symbol table is stored in the section header in the field reserved1. An indirect symbol table entry is simply a 32bit index into the symbol table to the symbol that the pointer or stub is referring to. The indirect symbol table is ordered to match the entries in the section.
