Where did the -C switch come from in package Linker?

   $ gnatlink -C
   gnatlink: -C.ali not found

(on the other hand, I just tried with one of my own GPRs and the command
line that gnatmake successfully passed to gnatlink was

   gnatlink foo.ali -C -o foo

The -C didn't get passed to the system linker.
