Subject: Re: [PATCH] Adding target rdos to GCC

That is intentional. The gthr-rdos.h file is part of libgcc. My

was to first patch gcc, then update the patches for newlib, and finally
libgcc. The gthr-rdos.h file would reference include-files part of
newlib,
so this is kind of circular. I also cannot define the thread model for
RDOS
unless I define this file.
I see a couple of possible solutions:
1. Keep as is. You cannot build libgcc at the current stage anyway, and
the
bootstrap must be built without threading
2. Add an empty gthr-rdos.h file until libgcc is done
3. Remove the threading-model for now, and add it with libgcc instead.
I propose option 3.
Is it enough to remove gthr.m4 change from the patch in this case?
Yes, for all practical purposes. There is a reference to thread-file in
config.gcc, when threading is enabled, which doesn't work for
bootstrapping
the compiler anyway.
Thanks for pointing it, I have also removed this reference.
Attached is the patch that has been committed to SVN. I have added
missing licence headers to new files and clean whitespace a bit.
