Definitely in 4.3.4:

$ pwd
/usr/local/ada-4.3/lib/gcc/i686-apple-darwin9/4.3.4/adainclude
$ egrep -iH "with.*blas|with.*lapack" a-*.ad[sb]
a-ngcoar.adb:with System.Generic_Complex_BLAS;
a-ngcoar.adb:with System.Generic_Complex_LAPACK;
a-ngrear.adb:with System.Generic_Real_BLAS;
a-ngrear.adb:with System.Generic_Real_LAPACK;

I started with Martin Dowie's 296 & 346:

IIRC, the changes were minor. If it would help, I have the last, 
independent set that I used before switching to BLAS/LAPACK in June, 
20009.
