Thanks for the patch. Can you tell us the version when native binutils fails to build? I regulary testing native binutils compile for different architectures and haven't seen the failure, yet. UCLIBC_HAS_OBSTACK is always enabled in my config.
Hi Waldemar,
I'm working with binutils-gdb master (or close to it). Obstack implementation has been updated in binutils in November 2015:
https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=commit;h=314dee8e...
So it should be present in latest binutils 2.26 (released on January 27).
Anton
best regards Waldemar
