+preprocessor symbol indicating the results of the test. That is done by
+calling @code{AC_DEFINE} or @code{AC_DEFINE_UNQUOTED}.
+
+By default, @code{AC_OUTPUT} places the symbols defined by these macros
+into the output variable @code{DEFS}, which contains an option
+@samp{-D@var{symbol}=@var{value}} for each symbol defined. Unlike in
+Autoconf version 1, there is no variable @code{DEFS} defined while
+@code{configure} is running. To check whether Autoconf macros have
+already defined a certain C preprocessor symbol, test the value of the
+appropriate cache variable, as in this example:
+
+@example
+AC_CHECK_FUNC(vprintf, AC_DEFINE(HAVE_VPRINTF))
+if test "$ac_cv_func_vprintf" != yes; then
+AC_CHECK_FUNC(_doprnt, AC_DEFINE(HAVE_DOPRNT))
+fi
+@end example
+
+If @code{AC_CONFIG_HEADER} has been called, then instead of creating
+@code{DEFS}, @code{AC_OUTPUT} creates a header file by substituting the
+correct values into @code{#define} statements in a template file.

@section Defining C Preprocessor Symbols
A common action to take in response to a feature test is to define a C
-preprocessor symbol indicating the results of the test. These two
-macros do that.
+preprocessor symbol indicating the results of the test. That is done by
+calling @code{AC_DEFINE} or @code{AC_DEFINE_UNQUOTED}.
+
+By default, @code{AC_OUTPUT} places the symbols defined by these macros
+into the output variable @code{DEFS}, which contains an option
+@samp{-D@var{symbol}=@var{value}} for each symbol defined. Unlike in
+Autoconf version 1, there is no variable @code{DEFS} defined while
+@code{configure} is running. To check whether Autoconf macros have
+already defined a certain C preprocessor symbol, test the value of the
+appropriate cache variable, as in this example:
+
+@example
+AC_CHECK_FUNC(vprintf, AC_DEFINE(HAVE_VPRINTF))
+if test "$ac_cv_func_vprintf" != yes; then
+AC_CHECK_FUNC(_doprnt, AC_DEFINE(HAVE_DOPRNT))
+fi
+@end example
+
+If @code{AC_CONFIG_HEADER} has been called, then instead of creating
+@code{DEFS}, @code{AC_OUTPUT} creates a header file by substituting the
+correct values into @code{#define} statements in a template file.
