Subject: [PATCH] arc: define _REENTRANT when -pthread is passed
|
||||
|
||||
The compiler is supposed to have the builtin defined _REENTRANT defined
|
||||
when -pthread is passed, which wasn't done on the ARC architecture.
|
||||
|
||||
When _REENTRANT is not passed, the C library will not use reentrant
|
||||
functions, and the latest version of ax_pthread.m4 from the
|
||||
autoconf-archive will no longer detect that thread support is
|
||||
available (see https://savannah.gnu.org/patch/?8186).
