- Subject: [PATCH v2 2/6] remove link.h checks
- Authentication-results: sourceware.org; auth=none
- References: <1383675811-3274-1-git-send-email-tromey at redhat dot com>
The removal of solib-sunos.c also removed the last user of various
macros defined by configure.
This patch removes the corresponding configure code.
2013-11-05 Tom Tromey <tromey@redhat.com>
* configure, config.in: Rebuild.
* configure.ac: Remove all link.h-related checks.
