No, I don't. The only explanation I can think of is that the command
'gcc' isn't picking up the Ada-aware compiler that you mean it to.

I did this:

   $ PATH=/opt/gcc-4.5.0-x86_64/bin:$PATH gprconfig --target=x86_64-apple-darwin10
   --------------------------------------------------
   gprconfig has found the following compilers on your PATH.
   Only those matching the target and the selected compilers are displayed.
      1. GNAT for Ada in /opt/gcc-4.5.0-x86_64/bin/ version 4.5 (default runtime)
      2. GCC-ASM for Asm in /opt/gcc-4.5.0-x86_64/bin/ version 4.5.0
      3. GCC-ASM for Asm2 in /opt/gcc-4.5.0-x86_64/bin/ version 4.5.0
      4. GCC-ASM for Asm_Cpp in /opt/gcc-4.5.0-x86_64/bin/ version 4.5.0
      5. GCC for C in /opt/gcc-4.5.0-x86_64/bin/ version 4.5.0
   Select or unselect the following compiler (or "s" to save): s

   You can regenerate the same config file in batch mode
    with the following command line:
   gprconfig --batch --target=x86_64-apple-darwin10

   Creating configuration file: x86_64-apple-darwin10.cgpr

but now when I say

   $ PATH=/opt/gcc-4.5.0-x86_64/bin:$PATH gprbuild --target=x86_64-apple-darwin10

instead of building (which it will if I delete
x86_64-apple-darwin10.cgpr) it says

   using project file test_extensions.gpr
   test_extensions.gpr:17:09: no languages defined for this project
   ada_math_build.gpr:15:09: warning: no compiler specified for language "ada", ignoring all its sources
   ada_math_build.gpr:17:25: warning: libraries are not supported on this platform
   gprbuild: "test_extensions.gpr" processing failed

I'm baffled.

Hmm, I tried

   $ gprconfig --config=Ada,,,/opt/gcc-4.5.0-x86_64/bin --target=x86_64-apple-darwin10

and then

   $ gprbuild --target=x86_64-apple-darwin10

and it was happy!
