ACX_FORTRAN_RUN_CHECK_SIZEOF in acx_fc_real_size.m4 does not check size of its argument
m4/acx_fc_real_size.m4 does not actually check for the size of the real type passed as its argument, similar to the analogous function
m4/acx_fc_integer_size.m4 for integer types.
Furthermore, when using this function, the bits division arithmetic,
AS_VAR_SET([acx_fortran_Sizeof],[`expr ]AS_VAR_GET([acx_fortran_Sizeof])[ / $acx_cv_c_char_bits`])]
was returning some shell errors stating that
expr was missing an operator, and that
/ is a directory. This seems to be due to the multiple nests of
eval which come with
AS_VAR_GET. It was easier to just do what was intended using the specifically designed method
AS_VAR_ARITH, rather than using the more general
The attached patch fixes these two issues.

The latest release of 1.0.5 fixes the second issue noted regarding the division arithmetic, but the first issue remains: the real type passed as the first argument to
ACX_FORTRAN_RUN_CHECK_SIZEOF is not checked for its size; rather, the specific type
real is checked.
The attached patch is updated for the latest release 1.0.5 to fix this issue.
