I ran gprconfig -v -v and have attached its results.

I think the correct one is /opt/gnat-gpl-2009/share/gprconfig which I attach.
I presume that the the relevant part is:
<!-- GNAT
To find the list of supported runtimes, we check the contents of
the directory. To be compatible with older versions of GNAT (3.16
for instance), we also accept lib/gcc-lib as the directory that
contains the runtime files.
Implementation note: we put two spaces after -adainclude $... in
the external_tool, because on windows the path will end with a
'\', and this would act as a quote for the following space.
-->
<compiler_description>
<name>GNAT</name>
<executable
prefix="1">(.*(-wrs-|-elf-|-eabispe-|avr-|elinos-linux).*)?gnatmake</executable>
<version>
<external>${PREFIX}gnatls -v</external>
<grep regexp="^GNATLS.+?(\d+(\.\d+)?)" group="1"></grep>
</version>
<variable name="gcc_version">
<external>${PREFIX}gcc -v</external>
<grep regexp="^gcc version (\S+)" group="1"></grep>
</variable>
<languages>Ada</languages>
<runtimes default="default,kernel">
<directory group="default"
>\.\./lib/gcc(-lib)?/$TARGET/$gcc_version/adalib/</directory>
<directory group="2"
>\.\./lib/gcc(-lib)?/$TARGET/$gcc_version/rts-(.*)/adalib/</directory>
</runtimes>
<target>
<external>${PREFIX}gcc -dumpmachine</external>
<grep regexp="[^\r\n]+"></grep>
</target>
</compiler_description>
Also,
gcc -v gives:
Using built-in specs.
Target: i386-apple-darwin10.2.0
Configured with: ../gcc-43-src/configure --prefix=/opt/gnat-gpl-2009
--with-gmp=/opt/gnu --with-mpfr=/opt/gnu --disable-multilib
--enable-languages=c,ada --disable-libada
Thread model: posix
gcc version 4.3.4 20090511 for GNAT GPL 2009 (20090511) (GCC)
gcc -dumpversion just gives:
4.3.4
gcc -dumpmachine gives:
i386-apple-darwin10.2.0
If I don't use PATH=/opt/gnat-gpl-2009/bin:$PATH
gcc -v tells me that, Target: i686-apple-darwin10
and
gcc -dumpmachine gives:
i686-apple-darwin10
That's about as far as I can get.
