This patch fixes another configure test issue when bootstrapping. sysdeps/i386/configure.in uses the obsolete AC_HEADER_CHECK macro to test for cpuid.h, and that macro tries to include various other standard headers (which come from the library, unlike cpuid.h which comes from the compiler, so aren't available when bootstrapping) in the test code it compiles. This patch changes the code to use AC_CHECK_HEADER, with the fourth argument used to prevent any default includes being used in the test. Tested x86_64 (native). 2012-03-07 Joseph Myers * sysdeps/i386/configure.in (cpuid.h): Use AC_CHECK_HEADER with no default includes instead of AC_HEADER_CHECK. * sysdeps/i386/configure: Regenerated.
