The Autoconf 2.57 doc says: Previous versions of Autoconf merely checked whether the header was accepted by the preprocessor. This was changed because the old test was inappropriate for typical uses. Headers are typically used to compile, not merely to preprocess, and the old behavior sometimes accepted headers that clashed at compile-time. If you need to check whether a header is preprocessable, you can use `AC_PREPROC_IFELSE' (*note Running the Preprocessor::). This scheme, which improves the robustness of the test, also requires that you make sure that headers that must be included before the HEADER-FILE be part of the INCLUDES, (*note Default Includes::). If looking for `bar.h', which requires that `foo.h' be included before if it exists, we suggest the following scheme: AC_CHECK_HEADERS([foo.h]) AC_CHECK_HEADERS([bar.h], [], [], [#if HAVE_FOO_H # include <foo.h> # endif ]) Thanks!
