+Subject: [PATCH] configure: macOS improvement (#197)
+
+* configure: fix shared library suffix on macOS
+
+See <https://lists.gnu.org/archive/html/libtool/2010-04/msg00020.html>,
+shrext_cmds is a command to be evaluated. Linux uses .so for both
+loadable and shared libraries (in terms of libtool), so the problem is
+not visible there, but on macOS this caused configure to literally look
+for
+
+libnspr4`test .$module = .yes && echo .so || echo .dylib`
+
+for the nss backend, while nss provides libnspr4.dylib.
