"LoadLibrary" does not exist per-se, existing functions are
LoadLibraryA and LoadLibraryW,
depending whether you use UNICODE or not. The windows headers just
#define LoadLibrary
to one of the existing functions, depending on your compilation flags.
The way the configure
script checks for a function in a library cannot work in this specific
case, it needs to include
windows.h to work.

These are part of the wldap32.dll library. Add -lwldap32 to the libraries.

For this, I have no idea. This might be mingw specific. You should
look at some advanced
compilation flags to rebase the octinterp DLL to another base address.
