1 You might also need to check for the existence of files. Before using
1 these macros, ask yourself whether a runtime test might not be a better
1 solution. Be aware that, like most Autoconf macros, they test a feature
1 of the host machine, and therefore, they die when cross-compiling.

1 -- Macro: AC_CHECK_FILE (FILE, [ACTION-IF-FOUND],
1 [ACTION-IF-NOT-FOUND])
1 Check whether file FILE exists on the native system. If it is
1 found, execute ACTION-IF-FOUND, otherwise do ACTION-IF-NOT-FOUND,
1 if given. The result of this test is cached in the
1 `ac_cv_file_FILE' variable, with characters not suitable for a
1 variable name mapped to underscores.

1 -- Macro: AC_CHECK_FILES (FILES, [ACTION-IF-FOUND],
1 [ACTION-IF-NOT-FOUND])
1 Executes `AC_CHECK_FILE' once for each file listed in FILES.
1 Additionally, defines `HAVE_FILE' (⇒Standard Symbols) for
1 each file found. The results of each test are cached in the
1 `ac_cv_file_FILE' variable, with characters not suitable for a
1 variable name mapped to underscores.
