Greetings,
I'm trying to port newlib-1.17.0 for my target. The target's compiler is
based on gcc 2.7.2.3, old yet fuctional.
When I try to make newlib, it tries to call the cross-compiler
(MyMachine-gcc) with size optimization flag (-Os), and it throws an error
with this message: "cc1: Invalid option `-Os'". My
target's gcc supports "-O1", "-O2" and "-O3".
When I configure and make newlib, how can I specify not to use "-Os" ?
Best regards
Navid
