/* This file turns a regular Windows PE image into a DLL. Because of
the complexity of this operation, it has been broken down into a
number of separate modules which are all called by the main function
at the end of this file. This function is not re-entrant and is
normally only called once, so static variables are used to reduce
the number of parameters and return values required.

will hold address of corresponding imported name. So, the solution is
de-vectorize these structures, making import locations be sparse and

For each reference of data symbol to be imported from DLL (to set of which

import fixup entry is generated. That entry is of type

(marked with __fuN_<sym> symbol, where N is integer), pointer to DLL name

name thunk. Symbol name thunk is singleton vector (__nm_th_<symbol>)
pointing to IMAGE_IMPORT_BY_NAME structure (__nm_<symbol>) directly

above: PE specification rambles that name vector (OriginalFirstThunk)
should run in parallel with addresses vector (FirstThunk), i.e. that they
should have same number of elements and terminated with zero. We violate

OS loader implemented the sane way: it goes thru OriginalFirstThunk and
puts addresses to FirstThunk, not something else. It once again should be
noted that dll and symbol name structures are reused across fixup entries
in windows9x kernel32.dll, so if you use it, you have two
IMAGE_IMPORT_DESCRIPTORS for kernel32.dll). Yet other question is whether
referencing the same PE structures several times is valid. The answer is why
