Which headers in particular?
All those that are needed by the unwinder, because now that is built as
well. newlib still needs glibc headers that it does not provide, right?
No, you should not be treating the configuration as a cross build.
Note that the configuration is treated as a cross build only as far as
allowing --with-headers.
On one hand your point is right that libgcov should find the headers if
--with-newlib is given; on the other hand, it seems like gcc disables
this on purpose, by defining -Dinhibit_libc if it finds --with-newlib.
The libc/sys/linux code is already LGPL so if you contribute an LGPL
solution, that is ok so long as everything works for a basic program.
Scripts for building x86-linux executables today won't be linking in
crti.o or crtn.o so you might look at making references weak so that
crti/crtn are not always required.
Yes, thanks.
