- Subject: [PATCH newlib]New configuration option disable wide orientation in Newlib
Hi,
C99 introduces wide orientation which is implemented in Newlib. This patch
introduces new option "--disable-newlib-wide-orient" allowing user to
disable it and reduce foot-print of binary. It also skips compilation of
wide orientation related files/functions. Is it OK?
The default behavior is not changed unless "--disable-*" option is specified
explicitly when configuring.
Any comments are welcome.
Thanks.
