Hello Robert,

Actually, to get verbose mode the simplest way to go with make is:
make VERBOSE=1

I have seen the -I.../src/osgPlugins/txp/. at some point while 
debugging. I need to restart the debug from original files. Still I 
think MINGW (Msys) compiler does not process includes the same way as 
Linux's gcc, I will also compare gcc versions.
