In ftp.iks-jena.de:/pub/mitarb/lutz/ada/types/ there is a set of mixin libs.

After a change in the (generic) source of double_linked_list_mixin.adb
gnatmake did not return. (Recompiling the Ada Compiler is problematic.)

(slightly shortend to squeeze it into 80 columns)

It's running in user space not in kernel space. (checked)

-gnats (Syntax check only) works.
-gnatt (Output parse tree) hangs.

Any hints?
