Expected:
If is defined in a file.h a
#include ..\relativepath\file1.h
directive with a relative path,
VFP it has to use that file, if it doesn't exist it has to produce an error.

Observed:
VFP looks within the folder of the file.h if a file "file1.h" exixts,
if it finds it then uses it, ignoring the "..\relativepath"

Repro:

* TESTBUG structure files
*   progtest.prg
*   myClasslib.vcx (myClass)
*   INCLUDEPATH1
*	incfile1.h
*   INCLUDEPATH2
*	incfile1.h	the bug file !
*	incfile2.h should to use ..\INCLUDEPATH1\incfile1.h
