#14 incorrect configuration files of gitk-renderer-opengl?

[Michael Randel]

When building the opengl renderer on msys/mingw it
seems that there are some incorrect configure files.
Because if I specify some compiler flags like

CFLAGS="$CFLAGS -I/Other/precompiled/include
-I/Other/precompiled/include/Inventor" ./autogen.sh ...

especially these include flags doesn't appear/apply
when building with 'make'. Based on this aspect other
gitk modules behave in the right way.
