* lib/autoconf/types.m4 (AC_CHECK_SIZEOF):

Report an error if the size cannot be determined even though
the type exists.
* lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
Check for `expr' arithmetic overflow, and for compilation failure,
and invoke a new argument $4 if either is discovered.
This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
(_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
