From 87936cd0130414cccc8a7427498dd5491ec2664f Mon Sep 17 00:00:00 2001 From: "Peter S. Mazinger" Date: Wed, 23 Mar 2011 17:08:07 +0100 Subject: errno and *_init cleanup Define a common view of __errno_location, __h_errno_location in common header and use that everywhere, __uClibc_main.c is no special. The rule adopted: for enabled threads we make in libc the __GI_x() variants strong, x() weak and (should) provide another strong x() in libpthread. If threads are disabled, even the __GI_x() variants are weak. _stdio_init,_stdio_term,_locale_init: make all hidden weak in common header Signed-off-by: Peter S.
