Subject: Work around conflict between <sys/ptrace.h> and <linux/ptrace.h>
X-Git-Tag: v4.9~180
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=0b4060f61f1bb101b5d8d084714b7d2feacdb199;p=strace

Work around conflict between <sys/ptrace.h> and <linux/ptrace.h>

Since glibc-2.18~39 <sys/ptrace.h> defines ptrace_peeksiginfo_args
which collides with <linux/ptrace.h>.

* configure.ac: Check for `struct ptrace_peeksiginfo_args' in
<sys/ptrace.h>.
* process.c: Work around potential conflict between <sys/ptrace.h>
and <linux/ptrace.h> by redefining ptrace_peeksiginfo_args.
* signal.c: Likewise.
* syscall.c: Likewise.
* util.c: Likewise.
