[Scip] nlpi and two pub_expression.h files

But they are distinguished by the directory where they are located.
scip/src should be the base directory and all files be referenced w.r.t.
this directory, cf. the SCIP Makefile.

No, I would suggest to get rid of Windows 7 instead. :-)

Did you try using cygwin or mingw? Then you could use the well tested
SCIP build system. There are also make files for using the M$ compiler
via mingw.
