Use strerror_r in safe_strerror if available
Also stores the result in a thread-local static variable and
changes the return value to a const char*.
This is already important because Guile creates threads and
Python can create threads, but with the patch series here:
https://gnutoolchain-gerrit.osci.io/r/c/binutils-gdb/+/176
GDB itself will create threads, too.
gdb/ChangeLog:
2019-10-31 Christian Biesinger <cbiesinger@google.com>
* configure: Regenerate.
* configure.ac: Check for strerror_r.
* gdbsupport/common-utils.h (safe_strerror): Change return value
to const char * and document that this function is now threadsafe.
* gdbsupport/posix-strerror.c (safe_strerror): Make buf
thread_local and call strerror_r, if available.
* utils.c (perror_string): Update.
(print_sys_errmsg): Update.
