Browse Source 
Reported by Dennis Clarke
<https://lists.gnu.org/r/bug-bison/2021-10/msg00005.html>.
In particular
<https://lists.gnu.org/r/bug-bison/2021-10/msg00023.html>.

* doc/bison.texi, examples/c/glr/c++-types.y,
* examples/c/bistromathic/parse.y tests/testsuite.h:
Define _XOPEN_SOURCE to 600, to get a strdup that works on Solaris.

* tests/glr-regression.at: Use strdup freely.
