I've set up my project file (attached below), with nothing really arcane
as far as I know, I even used the Project Wizard to help build it.  But
whenever I try to build the project I get the following error:

gnatmake -d -P/home/g315p/dsx/src/gtkgui/gtkgui.gpr dv.adb 
gcc -c -g -gnatQ -o
/home/g315p/dsx/src/gtkgui/./dtraq-client_data_viewer.o -gnato
-fstack-check -g `gtkada-config --cflags` -gnatA
/home/g315p/dsx/src/gtkgui/./dtraq-client_data_viewer.adb
gcc: cannot specify -o with -c and multiple compilations
gnatmake: "dtraq-client_data_viewer.adb" compilation error

process exited with status 4


I think it's got something to do with having the `gtkada-config
--cflags` in the switches configuration, because when I don't, I just
get ordinary compilation errors ("Can't find gtkada.ads").
