path: root/toolchain/uClibc/patches-0.9.30.1/400-gcc4.4-fixes.patch

The gcc-4.4 documentation still suggests that the compiler will automatically
do format checking for the standard format function prototypes, but it is now
also barking warnings suggesting that we add them for this lot too. So added.

usage() is also made static in answer to warnings about no prototype.
In __pthread_manager_event() we also have to drop the return statement,
else gcc will in turn complain about a non-returning function having one.

Once again all of these reduce the noise from gcc-4.4.
Replaces a few more (USE_TLS && HAVE___THREAD) with USE___THREAD while we need
to mess with them for this anyhow.
