+This is an obsolescent macro that checks that the C compiler supports
+the @option{-c} and @option{-o} options together. Note that, since
+Automake 1.14, the @code{AC_PROG_CC} is rewritten to implement such
+checks itself, and thus the explicit use of @code{AM_PROG_CC_C_O}
+should no longer be required.
