    configure.ac cleanups
    
    This patch removes the following obsolete macros
    - AM_PROG_CC_STDC (deprecated form of AC_PROG_CC)
    - AC_ISC_POSIX (the INTERACTIVE UNIX that needed it is long dead)
    - AC_C_CONST (assuming C89 support is safe today)
    - AC_HEADER_STDC (unused, and assuming C89 support is safe today)
