GPR linker-package troubles

[Shark8]

When I run the "Build All" command in GPS I get the following:

gnatlink C:\Programming\Projects\TAO_GL\obj\test.ali -lopengl32 -lglut32 --enable-stdcall-fixup -o C:\Programming\Projects\TAO_GL\test.exe
Warning: resolving _glClearColor@16 by linking to _glClearColor
Use --enable-stdcall-fixup to disable these warnings
Use --disable-stdcall-fixup to disable these fixups
Warning: resolving _glClear@4 by linking to _glClear

As you can see, the "enable-stdcall-fixup" option is included, yet the linker is behaving as if it were not. When I run gnatlink from the command-line and put the flag at the end things work fins, so I'm assuming the problem is that it is being treated as a switch rather than linker-option. (see below)

Currently the GPR's linker is as follows:
   package Linker is
      for Default_Switches ("ada") use ("-lopengl32", "-lglut32");
      for Linker_Options use ( "--enable-stdcall-fixup");
   end Linker;

I have also tried with the fixup-flag in the DEFAULT_SWITCHES list, no effect.
