Re: Re: newlib and libgloss questions

[<vishu27 at cox dot net>]

If I am to provide my own crt0.S and syscalls for newlib libc, should I recompile newlib by replacing the crt0.S and syscalls in newlib/sys/arm directory? Or is there a way to override the syscalls already compiled into libc. I thought that the *startupfiles in the specs file would do the job. 

Thanks
Vish
