[Bug fortran/29147] Bad overflow check in DATA statements

Fixed on trunk.  Although the patch would work
on 4.1, it isn't needed because I never fixed range
checking on 4.1.

Use -fno-range-check option.

I failed to not that your assertion that the error message
is misleading is incorrect.  The error message is actually
quite concise and accurate.  See section 5.2.10 of the F95
standard.

I submitted a patch that will allow you to do

gfortran -fno-range-check nonportable_code.f90

That's because every other compiler out there is broken :-)

The standard is quite clear that the BOZ is converted to an
integer with the kind type with the largest decimal range.
In your case that integer is kind=8, and  Z'' = 4294967295
which over flows the range of an integer(kind=4) constant.
