You aren't but I am. :( I just cut a new tarball with very modest
updates to the README's. It has a hello world ada and Makefiles
for the following targets:
+ i386/pc386
+ powerpc/psim
+ sparc/erc32
+ mips/jmr3904
The READMEs still reflect old tools but the Makefiles are up to date.
Any patches to READMEs or new ones would be welcomed.
ANd FWIW the merger of gnat into the main gcc means that the Getting
Started with GNAT/RTEMS manual needs to be folded into the main
Getting Started manual. So any help there is greatly appreciated.
There was a lot of detail in there that no longer applies.
