We appreciate the report anyway. The test suite is supposed to cope with the *absence* of C and/or C++ compilers, and with compilers that don't work at all, but the problem I saw in the testsuite.log you sent us—<sys/stat.h> being unusable in C++ only—is not feasible for us to distinguish from an autoconf bug from within the test suite. Older versions of Autoconf did not exercise the C++ compiler nearly as much in their test suites, which is why you may not have seen a problem before. I will consider whether there is something I could add to the release notes to warn people about test failures due to broken compilers. zw
