 After installation the gnatmake uses Apple's gcc (4.0.1), which does not
 have Ada. The workaround is to pass parameters via the command line (or
 via other means).

 Would it be possible to make the gnatmake use the gnat-gcc compilers out
 of the box? Or at least output a note when installing that you need to do
 this?

 Sample call and output:
 {{{
 % gnatmake hello.adb
 gcc -c hello.adb
 i686-apple-darwin8-gcc-4.0.1: hello.adb: Ada compiler not installed on
 this system
 gnatmake: "hello.adb" compilation error
 }}}

 Sample call with compiler defined:

 {{{
 % gnatmake --GCC=gcc-gnat-4.3 --GNATLINK="gnatlink --GCC=gcc-gnat-4.3"
 hello.adb
 gcc-gnat-4.3 -c -gnato -fstack-check -gnatE -gnaty hello.adb
 gnatbind -x hello.ali
 gnatlink hello.ali -fstack-check --GCC=gcc-gnat-4.3

 }}}
