Reentrant vs non-reentrant stubs

Making cross-environment for m68k-unknown-coff on i686-pc-linux-gnu.

The documentation in reent.h states that to use reentrant stubs (e.g.,
_open_r() ), make the following changes in (it doesn't state
which to change):

    set  syscall_dir to syscalls
    add -DREENTRANT_SYSCALLS_PROVIDED to target_cflags

To use non-reentrant stubs of the form, e.g., _open():

    set  syscalls_dir to syscalls

To use non-reentrant stubs of the form, e.g., open():

  add -DMISSING_SYSCALL_NAMES to target_cflags

My problems are:  Which  "target_cflags" doesn't exist in any, the closest thing is "CFLAGS", what to do?  What is the
default configuration "out of the box"?

Another problem, if I make a new install/build of newlib it makes fine.  If
I immediately do a "make all install" or a "make clean all install", it
error's out on the "__extension__ long long ..." statement in reent.h  I've
tried this under both a 2.95.3 gcc and 3.2 gcc.  ???

Thanks, Doug
