Re: demo-ppc405.sh and gnat

[Laurent GUERBY <laurent at guerby dot net>]

Hi Scott, I did put together some instructions to compile
successfully a cross GCC Ada compiler to an RTEMS
target based on 4.0 a few month ago:

http://www.rtems.com/phpwiki/index.php/RTEMSAda

I haven't tested it in a while.

To have tasking working you need to have an advanced thread library and
the corresponding Ada layer in the GNAT sources, RTEMS provides both.
