file-5.41 uses AC_PROG_CC, and was generated with autoconf 2.69. That
oldish version of autoconf does not check the C standard when AC_PROG_CC
is called, and standard-specific macros must be called instead:
AC_PROG_CC_C89, AC_PROG_CC_C99, or AC_PROG_CC_STDC.
So we would need to patch configure.ac to call either of those options,
and then we'd have to autoreocnf.
However, that would autoreconf with our autoconf, version 2.71. In that
version, AC_PROG_CC always check what C standards are available and sets
the appropriate ac_cv_XXX variables, and the previous macros,
AC_PROG_CC_C89, AC_PROG_CC_C99, and AC_PROG_CC_STDC are deprecated.
So it turns out that we just need to autoreconf.
