Under cygwin, gcc 4.3.4:
---------------------------
$ gnatmake -gnat05 main.adb
gcc -c -gnat05 main.adb
gnatbind -x main.ali
gnatlink main.ali
/usr/lib/gcc/i686-pc-cygwin/4.3.4/../../../../i686-pc-cygwin/bin/ld: 
cannot find -lgnalasup
collect2: ld returned 1 exit status
gnatlink: error when calling /usr/bin/gcc.exe
gnatmake: *** link failed.

under GPL 2010 gnat:
--------------------
gnatmake -gnat05 main.adb
gcc -c -gnat05 main.adb
gnatbind -x main.ali
gnatlink main.ali
-----------------------

So, you'r right, it does not look like I needed to build the lapack and 
blas libraries if using gnat gpl 2010.  That is good. I assume then 
these libraries come in with gnat.

thanks
