+Subject: [PATCH] Compare linker/compiler output with their default output
+
+linker and compiler may have noisy output by default, making
+acx_pthread.m4 believe that pthread options that it tries are ignored
+as invalid.
+
+Record default compiler and linker output and see if adding pthread
+option changes that, instead of assuming that linker and compiler are
+silent by default.
