__getreent in libgloss

[Stefan Wallentowitz]

Dear all,

I am currently porting (baremetal) libgloss/newlib for OpenRISC (or1k). 
I want to use dynamic reentrancy and think I basically understood it.
Can you please confirm that the following steps are correct and the 
proper way to go:

I specify __DYNAMIC_REENT__ for the machine in 
newlib/libc/include/sys/config.h. I also set 
newlib_cflags="${newlib_cflags} -DREENTRANT_SYSCALLS_PROVIDED " and 
syscall_dir=syscalls in configure.host for the target. By default newlib 
takes __getreent() and I can overwrite __getreent to my own function. 
Where should I do this? I set it in config.h (#define __getreent 
or1k_getreent), but then I also need to define the external function 
(extern struct _reent *or1k_getreent(void)), correct?

Thanks for your help.

Best regards,
Stefan
