Earlier FORTRAN compilers generated the minimum number of spaces

Intel provides a "-standard-semantics" command-line option to produce
the earlier behavior.  Is there any equivalent option for GNU Fortran?


That is a misfeature of Intel Fortran - not the option, but its name.
There is nothing standard about that semantics - not even in Fortran IV.

The standard is very clear that separators must include a comma, spaces
or both - and beyond that is unspecified.  Older compilers had a huge
variety of behaviours, and current ones are fairly variable.
