// This macro is equivalent in part to the assembly language TestFor macro,

// if (TestForBaseAddr(GrandCentralExists)) { }

// table in one easy-to-read operation. Assuming that the corresponding BasesValid
// flag is true, the base address can be recovered directly by its field name in
// the DecoderInfo record. The macro handles all the arcane offsets, casts, and
// dereferences. Example:
// void *gcBase = GetUnivInfoBaseAddr(GrandCentralAddr);
