>Description:
The Ada language front-end is written in Ada. Building it requires an Ada compiler. For bootstrapping, only a partial compiler is required. The gcc3-ada package uses the ADA_BOOT compiler to compile everything when only the GNAT binary gnat1, a copy of gnatbind, and a compiler driver which can deal with Ada input are required. A minor change to the Makefile allows this to be accomplished (patch provided).
>How-To-Repeat:
Build ADA_BOOT compiler under 1.6.1-STABLE and try to build package using it under CURRENT.
