+# Test for PR 307: depcomp with depmode=dashmstdout libtool race condition
+# Report from Laurent Morichetti.
+# (Also exercises check_LTLIBRARIES.)
+#
+# == Report ==
+#  The dashmstdout depmode calls libtool in parallel to generate the
+#  dependencies (with -M flag) and to build the objfile (both have
+#  --mode=compile and -o).
+#  The process with 'libtool --mode=compile .* -M' can corrupt the objfile
+#  as none is generated by the compiler.  Since --mode=compile and -o are
+#  set libtool assumes that a objfile should be generated and will execute
+#  invalid $mv & $LN_S.
+#
+# == Fix ==
+#  Now 'depcomp' never compute dependencies in the background, as this can
+#  cause races with libtool.  Compute the dependencies after the actual
+#  compilation.
