SCons on MSys2 does not recognize windows paths as absolute #3254

On Windows, MSYS2 (64 bits version), SCons 2.5.1, calling pkg-config for gtkmm has this output:

$ pkg-config gtkmm-3.0 --cflags --libs
-mms-bitfields -pthread -mms-bitfields -IC:/msys64/mingw64/include/gtkmm-3.0 -IC:/msys64/mingw64/lib/gtkmm-3.0/include -IC:/msys64/mingw64/include/atkmm-1.6 -IC:/msys64/mingw64/include/gdkmm-3.0 -IC:/msys64/mingw64/lib/gdkmm-3.0/include -IC:/msys64/mingw64/include/giomm-2.4 -IC:/msys64/mingw64/lib/giomm-2.4/include -IC:/msys64/mingw64/include/pangomm-1.4 -IC:/msys64/mingw64/lib/pangomm-1.4/include -IC:/msys64/mingw64/include/glibmm-2.4 -IC:/msys64/mingw64/lib/glibmm-2.4/include -IC:/msys64/mingw64/include/gtk-3.0 -IC:/msys64/mingw64/include/cairo -IC:/msys64/mingw64/include -IC:/msys64/mingw64/include/pango-1.0 -IC:/msys64/mingw64/include/fribidi -IC:/msys64/mingw64/include/atk-1.0 -IC:/msys64/mingw64/include/cairo -IC:/msys64/mingw64/include/cairomm-1.0 -IC:/msys64/mingw64/lib/cairomm-1.0/include -IC:/msys64/mingw64/include/cairo -IC:/msys64/mingw64/include/pixman-1 -IC:/msys64/mingw64/include -IC:/msys64/mingw64/include/freetype2 -IC:/msys64/mingw64/include -IC:/msys64/mingw64/include/harfbuzz -IC:/msys64/mingw64/include/libpng16 -IC:/msys64/mingw64/include/sigc++-2.0 -IC:/msys64/mingw64/lib/sigc++-2.0/include -IC:/msys64/mingw64/include/gdk-pixbuf-2.0 -IC:/msys64/mingw64/include/libpng16 -IC:/msys64/mingw64/include -IC:/msys64/mingw64/include/glib-2.0 -IC:/msys64/mingw64/lib/glib-2.0/include -IC:/msys64/mingw64/include -LC:/msys64/mingw64/lib -lgtkmm-3.0 -latkmm-1.6 -lgdkmm-3.0 -lgiomm-2.4 -lpangomm-1.4 -lglibmm-2.4 -lgtk-3 -lgdk-3 -lgdi32 -limm32 -lshell32 -lole32 -Wl,-luuid -lwinmm -ldwmapi -lsetupapi -lcfgmgr32 -lz -lpangowin32-1.0 -lpangocairo-1.0 -lpango-1.0 -lfribidi -latk-1.0 -lcairo-gobject -lgio-2.0 -lcairomm-1.0 -lcairo -lsigc-2.0 -lgdk_pixbuf-2.0 -lgobject-2.0 -lglib-2.0 -lintl

when passed to scons ParseConfig, scons does not understand the -IC: as relative path, so build commands appear as:

g++ -o gui/key_bindings.o -c -g3 -pthread -mms-bitfields -Iglobals -Igui -I. -Igui/C:/msys64/mingw64/include/gtkmm-3.0 -Igui/C:/msys64/mingw64/lib/gtkmm-3.0/include -Igui/C:/msys64/mingw64/include/atkmm-1.6 -Igui/C:/msys64/mingw64/include/gdkmm-3.0 -Igui/C:/msys64/mingw64/lib/gdkmm-3.0/include -Igui/C:/msys64/mingw64/include/giomm-2.4 -Igui/C:/msys64/mingw64/lib/giomm-2.4/include -Igui/C:/msys64/mingw64/include/pangomm-1.4
17:15 <reduz> -Igui/C:/msys64/mingw64/lib/pangomm-1.4/include

Notice the -Igui/C: on each include, meaning it thinks it's relative. I could understand this for Cygwin, but this is MSys+Mingw

This is with the simplest project possible, calling Environment() and then ParseConfig and building any file results in this behavior.

Please try SCons 3.0.1 as scons 2.5.1 is pretty old. Also please bring the discussion to the user's mailing list per "# Please bring your issue to the SCons users mailing list before filing an issue here"
