Ada source files can end in "ada", today, or in just
anything.  You can use GNAT's gnatname and gnatchop to convert
Ada source files to Ada source files that have one compilation unit
per file, ending in "ads" for specs and in "adb" for bodies.
This is how GNAT/GCC wants them.

Alternatively, you can write a ton of pragmas telling GNAT
where to find a unit, or add this info to a project file IIRC.

The "GNAT [GPL] User's Guide" has some background information.

"10 Handling Arbitrary File Naming Conventions Using `gnatname'
**************************************************************

"10.1 Arbitrary File Naming Conventions
======================================

"The GNAT compiler must be able to know the source file name of a
compilation unit.  When using the standard GNAT default file naming
conventions (`.ads' for specs, `.adb' for bodies), the GNAT compiler
does not need additional information.

"..."

Something like this should work:

mkdir for-gnat
cd for-gnat
for file in <list-of-original-files> loop
   gnatchop [-r] -w  file
end loop
