Problems passing compiler parameters in GPR files

[Lucretia <laguest9000@googlemail.com>]

Hi,

I've been updating my bare bones project (https://github.com/Lucretia/bare_bones) to use a later version of GNAT (currently, 4.9).

I've run into a problem passing gnatmake parameters in the GPR files. I've set -gnaty-s and -gnatM120 for example and they both get ignored unless I add them to the i586-elf-gnatmake commandline.

I've managed to get the parameters to be recognised by doing this in the bare_bones.gpr:

   package Builder is
      Ada_Switches := ("-gnat2012", "-gnata", "-gnato", "-gnatE",
                       "-gnaty", "-gnaty-s", "-gnatyO", "-gnaty+M120", "-gnatyx",
                       "-gnaty+d", "-gnatv");
   end Builder;

   package Compiler is
      Ada_Switches := ("-ffunction-sections", "-fdata-sections") & Builder.Ada_Switches;
      --                         "-gnat2012", "-gnata", "-gnato", "-gnatE",
      --                         "-gnatyN", "-gnaty", "-gnaty-s", "-gnatyO", "-gnatyM120", "-gnatyx",
      --                         "-gnaty+d", "-gnatv");

I've no real clue why not having only those in the builder don't work. Can anyone explain?

Thanks,
Luke.
