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
