When you specify --disable-newlib-supplied-syscalls, the code in libgloss/arm is still compiled and there is a crt0.o there.
This does not seem to be the case in 1.13.0. I get rdimon-crt0.o, rdpmon-crt0.o, and redboot-crt0.o, but I'm not using any of these monitors. I will try with the CVS code when I have some time, since apparently I ought to be using that anyway.
The missing crt0.o appears to be a typo on my part. The crt0.o is only being built when newlib-supplied-syscalls are enabled, but this doesn't make sense since libc/sys/arm provides a crt0.o in that case. I have just made a patch to the CVS sources. Please try it out.
One more thing has to be done to libgloss/arm/configure.in; the AC_SUBST macros for the relevant variables are missing, and so they are never substituted in the Makefile. Just add these lines and I think it will work:
AC_SUBST(BUILD_CRT0_TRUE) AC_SUBST(BUILD_CRT0_FALSE)
I tried this myself but couldn't manage to regenerate configure from configure.in ("aclocal && autoconf" didn't work), so I just hand-edited configure and added the substitution code, and then everything worked.
