+/* .idata section description
+
+ The .idata section is the import table. It is a collection of several
+ subsections used to keep the pieces for each dll together: .idata$[234567].
+ IE: Each dll's .idata$2's are catenated together, each .idata$3's, etc.
+
+ .idata$2 = Import Directory Table
+ = array of IMAGE_IMPORT_DESCRIPTOR's.
+
+ DWORD Characteristics; - pointer to .idata$4
+ DWORD TimeDateStamp; - currently always 0
+ DWORD ForwarderChain; - currently always 0
+ DWORD Name; - pointer to dll's name
+ PIMAGE_THUNK_DATA FirstThunk; - pointer to .idata$5
+
+ .idata$3 = null terminating entry for .idata$2.
+
+ .idata$4 = Import Lookup Table
+ = array of array of pointers to hint name table.
+ There is one for each dll being imported from, and each dll's set is
+ terminated by a trailing NULL.
+
+ .idata$5 = Import Address Table
+ = array of array of pointers to hint name table.
+ There is one for each dll being imported from, and each dll's set is
+ terminated by a trailing NULL.
+ Initially, this table is identical to the Import Lookup Table. However,
+ at load time, the loader overwrites the entries with the address of the
+ function.
+
+ .idata$6 = Hint Name Table
+ = Array of { short, asciz } entries, one for each imported function.
+ The `short' is the function's ordinal number.
+
+ .idata$7 = dll name (eg: "kernel32.dll"). (.idata$6 for ppc)
