From 5df4854ed21641e5f82e17677fc385e05480ce3a Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Thu, 11 May 2017 14:15:26 +0000 Subject: Condition some sys/ucontext.h contents on __USE_MISC (bug 21457). Continuing the fixes for namespace issues arising from sys/ucontext.h, this patch conditions various definitions, that are not needed for defining mcontext_t / ucontext_t, on __USE_MISC, so they do not appear in strict POSIX modes. This patch is non-exhaustive; that is, it only conditions straightforward cases and there may be more such definitions that can be conditioned for these and other architectures, to be dealt with later in separate patches. Also, using __USE_MISC is the minimum change for these definitions where they conflict with POSIX; some headers already have __USE_GNU conditionals on similar definitions of names for registers. The patch specifically does not do anything with definitions in bits/sigcontext.h, and nor does it condition any inclusions of bits/sigcontext.h even where in fact that is not needed on some architectures for the definitions of mcontext_t / ucontext_t. As other namespace issues in these headers remain, this patch does not fix bug 21457, nor allow any XFAILs to be removed. Tested with build-many-glibcs.py.
