+Subject: [PATCH] Programs/pgmprivs_linux.c: fix build with gcc < 5
+
+Build with gcc < 5 is broken since version 6.2 and
+https://github.com/brltty/brltty/commit/8ce262f2c15f10a40d9cbae0b3c88b466970a055:
+
+./pgmprivs_linux.c: In function 'getPrivilegeParameterNames':
+./pgmprivs_linux.c:2220:3: error: array initialized from non-constant array expression
+   static const char *const names[] = NULL_TERMINATED_STRING_ARRAY(
+   ^
+
+Build was partially fixed since
+https://github.com/brltty/brltty/commit/8ae78dd560d00c5074158f90be5ac8dac80183db
+but it forgot to update pgmprivs_linux.c
