Description of problem: autoconf 2.53 (as distributed with Red Hat 8) may have a bug. Running autoconf on the following two-line configure.in: AC_INIT(test, 0) AC_CHECK_SIZEOF(int, 4) generates a configure script that fails on gcc 3.0.4 (as distributed with Red Hat 7.2). config.log has been attached. Version-Release number of selected component (if applicable): 2.53 How reproducible: Always Steps to Reproduce: 1. Create two-line configure.in as described above on a Red Hat 8 system. 2. Run 'autoconf'. 3. Move generated 'configure' script to a Red Hat 7.2 system. 4. Run './configure'. Actual results: checking size of int... configure: error: cannot compute sizeof (int), 77 Expected results: checking size of int... 4 Additional info: --- Example: $ gcc -v Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/3.0.4/specs Configured with: ../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --enable-shared --enable-threads=posix --disable-checking --host=i386-redhat-linux --with-system-zlib Thread model: posix gcc version 3.0.4 (Red Hat Linux 7.2 3.0.4-1) $ ./configure <output deleted> checking size of int... configure: error: cannot compute sizeof (int), 77 $ export CC=kgcc $ kgcc -v [p@awacs autoconf-bug]$ kgcc -v Reading specs from /usr/lib/gcc-lib/i386-glibc21-linux/egcs-2.91.66/specs gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release) <output deleted> checking size of int... 4 $
