This patch removes the documentation of debug switches that are not used
anymore by gnat2why, and are thus free for other uses.
In frontend.adb, there was a now obsolete reference to -gnatd.H, which
is also removed.
Tested on x86_64-pc-linux-gnu, committed on trunk
2013-10-14 Johannes Kanig <ka...@adacore.com>
* debug.adb: Release now unused debug switches that were only
relevant for gnat2why backend, not the frontend
* frontend.adb (Frontend) Do not stop when -gnatd.H is present,
was unused
