+# FIXME: The GCC team has specific needs which the current Autoconf
+# framework cannot solve elegantly. This macro implements a dirty
+# hack until Autoconf is able to provide the services its users
+# need.
+#
+# Several of the support libraries that are often built with GCC can't
+# assume the tool-chain is already capable of linking a program: the
+# compiler often expects to be able to link with some of such
+# libraries.
+#
+# In several of these libraries, workarounds have been introduced to
+# avoid the AC_PROG_CC_WORKS test, that would just abort their
+# configuration. The introduction of AC_EXEEXT, enabled either by
+# libtool or by CVS autoconf, have just made matters worse.
+#
+# Unlike the previous AC_NO_EXECUTABLES, this test does not
+# disable link tests at autoconf time, but at configure time.
+# This allows AC_NO_EXECUTABLES to be invoked conditionally.
